* Afterglow (G14) is removedGabriel Schneider27 hours
| | | | | | | | | | | The user, looking at the lapis showcase: "one of the animations is like a flashing on the whole pane or something, that is really bad, just remove it". Every changed cell glowing meant a pane whose whole text changed (a file opened, a +Search refilled, a terminal's output) lit up at once: replacing a pane's text took its mean brightness from 38 to 70 and back over 250 ms. Gone like Ripple and Glitch: the builtin, the setting, its Chrome fx bit, the GUI's diff state and decor, the test, and the docs, which keep the user's words.
* The focused cursor rides with a moving pane, and a focus change glides to ↵Gabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | the new one G3's springs now keep the cursor's place in its pane: a pane that moves in the layout carries them, and the quad is drawn through the pane's presented box (its transition track), so through a slide, zoom or drag the cursor rides with the text, and with no transition it lands with it. A focus change, to another pane or into a column's or the workspace's tag, glides from where the cursor was drawn to the new place instead of snapping, unclamped while it crosses. While panes move the cursor is drawn as the overlay quad instead of vanishing (golden 18-mid-transition re-recorded for that: the only change is the quad, gliding into the new column's tag). Lapis: a tag plaque starts flush against its grip's button, the scroll gap between them part of the plaque, so grip and plaque read as one piece, on pane and column rows alike; below the button's row the grip keeps its band. Themes without plaques are unchanged (their grip band and tag band are one colour, no sliver).
* effects.md: the terminal track's T5 and T6, and the byte budget, not builtGabriel Schneider27 hours
|
* T3: PanelCurtain wipes behind a soft edge two cells wideGabriel Schneider27 hours
| | | | | | | The curtain's glyph slide becomes a wipe: the new grid behind a head that crosses the pane, the old ahead, and between them two columns whose colours step from the old ground to the new in OKLab (CharSource.edge). Only the head's columns change from frame to frame.
* T7: the scroll thumb flashes as a terminal pane scrollsGabriel Schneider27 hours
| | | | | | | ThumbFlash (off by default) brightens a body's scroll thumb toward the ink when its view moves and fades it back over 250 ms, truecolor only. The tty present path now clears shell_continuous once before its effects and each effect only raises it, so the trail and the flash no longer mask each other.
* T1: ChipShadow, a terminal's notice chips cast a cell's shadowGabriel Schneider27 hours
| | | | | | | | | | | | | ChipShadow on|off (off; the tty shell's, §9.2 T1): each notice chip casts a shadow one cell right and one down inside its own pane's body: on a blank cell a half block (▌ right, ▀ below, ▘ at the corner) in a colour 35% darker than the ground (OKLab), so the shadow is half a cell thick; under text the ground itself darkened. Never the cursor's cell, a selection, a tag or another chip; truecolor terminals only. Tests: the shadow lies right of or below the chip, never in it; nothing with it off or without truecolor. Snapshots unchanged. Feel review: .scratch/render/tty/shadow/.
* T4: the terminal's dissolve swaps cells in ordered (Bayer) orderGabriel Schneider27 hours
| | | | | | | | | | | | | animation.dissolveRevealed (the tty compositor's dissolve and the pointer mapping that follows it) swaps each changed cell once at its place in a 4x4 Bayer matrix, shifted by the pane's serial so two panes differ, instead of at a hashed noise threshold: the new content comes in as an even patterned screen (§9.2 T4). Endpoints stay exact. Tests: a 4x4 block reveals exactly t x 16 cells at t = 1/4, 1/2, 3/4. Snapshots unchanged. Feel review: .scratch/render/tty/dissolve/ (the matrix over two real frames; the recorded session's pane did not animate, noted in docs/effects.md).
* T2: JumpTrail, a terminal cursor's jump leaves a short fading trailGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | JumpTrail on|off (off; the tty shell's, §9.2 T2): a jump of three cells or more leaves three to five cells of trail behind the cursor along its path, their ground mixed toward the text's colour in OKLab (most beside the cursor), fading out over 120 ms. Truecolor terminals only (vaxis's answer, or COLORTERM truecolor/24bit); never the cursor's own cell, a selection or anything outside the focused pane's body; none under Motion off. It rides the continuous path (Pardes.shell_continuous) while it lasts; a few cells of output a frame. docs/effects.md opens the terminal track with the audit under decision 2 (keep and polish, remove nothing). Tests: a ten-cell jump lights 3 to 5 cells behind the cursor on its row, gone by 120 ms; a one-cell step and a terminal without truecolor light none. Feel review: .scratch/render/tty/trail/ (a real tty session replayed through pyte at 60 fps).
* G14: Afterglow, changed text glows a moment and fadesGabriel Schneider27 hours
| | | | | | | | | | | | | | Afterglow on|off (off, a pixel shell's; Chrome.fx bit 4): the GUI keeps the grid it last drew and when each cell changed; a body cell whose text changed glows in the theme's accent, at most 18% and under the text's contrast floor, fading with an ease-out over 250 ms, one flat rectangle a run of cells that changed together; never a tag or a grip, the cursor or a selection; a scrolled body (its first line moved) starts over rather than lighting up whole. On the continuous path while anything glows. Tests: three changed cells glow as a run of two (the cursor's left out), gone by 250 ms, a scroll lights nothing. Gates as before; goldens byte-identical. Feel review: .scratch/render/afterglow/.
* G13: Parallax, lapis's dots drift with the text at a quarter of its speedGabriel Schneider27 hours
| | | | | | | | | | | | | | | Parallax on|off (off, a pixel shell's; Chrome.fx bit 3). A body region carries its first line (Region.line, a file's scroll or a terminal's grid offset; the wire's region record grows a u32). The GUI offsets each body's page dots by a quarter of its line in rows, and of G6's glide offset while one runs, so the pattern drifts with the text and settles with it; the cell shader reads it from the instance's serial slot, whose per-cell dissolve noise G7 left unused (the dead noise code goes). Tests: a scrolled body tells its line; the shift handed to the shader is a quarter of it within the dots' period. Measured in a capture: four lines move the dots 13 px (140 px / 4 mod 22). Gates as before, goldens byte-identical. Feel review: .scratch/render/parallax/.
* G12: Occlusion, pane bodies darkening faintly toward their edgesGabriel Schneider27 hours
| | | | | | | | | | | Occlusion on|off (off, a pixel shell's; Chrome.fx bit 2 — the glow bits field is now `fx`): four soft strips cast from just outside each pane body inward, clipped to the body and round a cursor, black pre-warped to linear light, 2% at most (§9.1) and under the lift's contrast ceiling, in the pane's own group. Tests: the shade stays inside the body, off the cursor, at most 2%. Gates as G11. Feel review: .scratch/render/occlusion/ (with an x40 diff).
* G11: HoverGlow, a soft underline of light under a look-hover's wordGabriel Schneider27 hours
| | | | | | | | | | | | | | HoverGlow on|off (off, a pixel shell's; Chrome.glows bit 1, SelectionGlow bit 0 now that there are two): under the word a look-hover would open (its cells in the affordance's tint) a strip three logical pixels tall along its foot, blurred by one, in the theme's accent, at most 22% and under the text's contrast floor, fading in over 80 ms; kept to the bodies and split round a cursor. glowBlocks serves G9 and G11. The strip is cast from a row away so addSoft's caster cut-out misses it. Tests: the glow comes up by 90 ms and never falls on the cursor's cell. Gates as G10 (a loaded machine shifted the GUI goldens a scene once; a rerun matched 01-08). Feel review: .scratch/render/hover/.
* G10: the theme's chrome fades through OKLab, easing in and outGabriel Schneider27 hours
| | | | | | | | | | | | ChromeTheme.interpolate mixes each colour in OKLab (colors.mixOklab), so a fade between hues keeps its lightness instead of going dark and muddy mid way; animation.Fade eases it in and out (smooth), and one retargeted mid fade eases out from where it shows, so it never stalls. Still 10 frames (160 ms). The page, text and syntax colours change at once as before. Tests: OKLab round-trips its ends exactly and keeps a red-to-green mid-way brighter than the sRGB mix. Gates as G9 (no golden moved). Feel review: .scratch/render/crossfade/.
* G9: SelectionGlow, a soft halo round the body's selectionGabriel Schneider27 hours
| | | | | | | | | | | | | | | SelectionGlow on|off (off; a pixel shell's, Chrome.selection_glow): each block of selected rows in a pane body casts Lift's soft kind in the selection's own colour, the block its caster (never touched) and a cursor beside it joined to the caster; clipped to the bodies (never a tag or a grip); at most 22% (§8.2), less where the text round it would drop below min(its contrast, 4.5); fading in over 100 ms with an ease-out, on the core's continuous path (shell_continuous); none while panes move. Blocks come from the cells in the theme's selection colour (documented). Tests: the halo's colour, its clip to the body, nothing at its first frame and up to its cap after 100 ms, fading done. Gates as G8. Feel review: .scratch/render/selection/.
* G8: a notice leaves quicker than it arrivesGabriel Schneider27 hours
| | | | | | | | | | | | | The notice chip's motion was mostly there (a drop easing out on the Motion flavour, a dissolve easing in, Lift's shadow in tier 4 at its fade). Its dissolve took 300 ms against a 180 ms fall, the wrong way round for §8.1 (leaving quicker than arriving, 100 to 160 ms): MessageDissolve now defaults to 150. The field comments had the two easings swapped; the stack test pins a longer dissolve for the case it checks. docs/config.md and docs/effects.md say so. Tests: both timings in their bands, leaving quicker. Gates as G7 (no golden moved). Feel review: .scratch/render/notices/.
* G7: a moving pane casts a shadow, a retargeted move keeps its speed, a ↵Gabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | dissolve crossfades - Track.launch: a move retargeted mid-way (Presentation.sync) starts at the old move's speed along the new one's longest side (carriedLaunch, Motion.easeFrom/speedFrom), so a second change during a slide bends the motion instead of stopping it dead. The macOS track ABI grows the float (pardes.h, 48 bytes; its reserved byte is named motion, as in Zig). - A pane that slides, zooms or rises casts Lift's soft shadow at sin(pi x progress) of its strength, on the other panes' bodies and rails alone, under the same contrast ceiling, carried by its track. - The GUI's PanelDissolve is a crossfade: the new cell drawn first, the old one over it at 1 - progress, premultiplied, on the blending cell pipeline for such groups (new cells now emitted before old ones, as the old layers already came after the new). sRGB blend, not linear light (documented). The tty keeps its per-cell swap. Presentation.zig's and animation.zig's tests were not in any test root; pardes.zig's test block now takes them in. Tests: a retargeted move carries its speed and still lands exactly; a moving pane's shadow is clipped off every tag, grip and its own body, none at the start or the landing, most mid-way. GUI golden 18 changes by the shadow (frame 6 of a slide). Gates as G6. Feel review: .scratch/render/transitions/.
* G6: a wheel's notch scrolls the core at once and the picture glides after itGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | A mouse wheel's notch (SDL's whole-number step, notchOf) scrolls the core by its lines at once, so keys and clicks act where the text is, and the picture follows on the Motion flavour's spring at half again its pace, critically damped whatever the flavour (text never passes its mark), carried from its current speed (animation.Spring.carry), so notches in a row flow on. How far the rows moved is measured on the next frame against the last (Glide.measure: a wrapped line's rows, a terminal's output, with a couple of rows' slack for the cursor's line and its number); the rows that left are kept, nearest first, and drawn in the gap the lag opens; the lag is never more than the body's height. A touchpad's fractions move the picture under the finger as before; `Motion off` lands a notch at once; a PDF page scrolls as before. The glide runs on the core's continuous path: Pardes.shell_continuous keeps frames coming every loop while it moves and carries a virtual clock with it; idle, nothing. The test feed takes wheel events (ESC]777;mouse;wheel;<amount>;<x>;<y>BEL). Tests: notch vs fraction; a carried spring keeps its speed and never passes its mark; a notch over two-row lines lags two rows, keeps the rows that left, settles frame by frame and leaves the continuous path, and lands at once with Motion off. Gates as G5. Feel review: .scratch/render/scroll/glide-{smooth,crisp,bouncy,off}{,-quarter}.mp4 and strips (a notch down, three, then two up).
* G5: lapis, 0x4200.cafe's manuscript, as a theme with its ornamentGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A native theme `lapis` (src/themes/lapis.zig) from web/theme/lapis.css: a lapis-deep page, lapis tags with gold names, vellum text, vermilion rubrics, gold rules and a vermilion tag rule, gold selection in lapis ink. Its ornament is the theme's new `decor` (colors.Decor), drawn by a pixel shell inside the chrome it already has (decision 1), all of it off every focus indicator: - page_dots: the site's gold dot grid (#e8c46a22, 22 px), drawn by the cell shader on page-coloured cells alone (flag 0x10000000), so it lies under the text and never under a selection, a tag or the cursor; fixed to the window, a page the panes lie on. - rail_checker: the dither frame's gold and lapis checker in the scroll track (a decor kind, flag 0x08000000), anchored to its rail; the thumb stays solid gold. - tag plaques (tag_border, tag_shadow, tag_stripe): every tag a raised plaque inside its own band, the site's trail: a 2px gold frame and a hard 5px vermilion shadow down and right, both within the band's rows and columns (down, what the slack under the text leaves), so no shadow reaches a body, a grip or the next pane. The focused pane's plaque is the code window's title bar, gold and lapis stripes of 2px, its words on plates of the focused ground; unfocused ones are plain; column and workspace tags take the object-label language (1px frame, 2px shadow toward the page). Drawn as decor under the cells (a group's under range), with blank tag cells see-through and the cells blended premultiplied (pipeline_over) on such frames; opaque windows only. - title_shadow: the titles' vermilion offset shadow under a file name's letters, sampled in the cell shader inside the letters' own cells (flag 0x08000000), none on a cursor. Chrome carries the decor (decor_*, name_ink, active_name_ink); a theme file folds a nested decor literal field by field. Left out, with why, in docs/effects.md: the fonts, the ornaments, a decor crossfade, and in the tty anything but the colours (a tag row has no spare cell for a shadow). An empty column is the page. The effect id is masked to 27 bits (ui.vert/ui.frag) for the fifth flag. Tests: the cell flags land only on page ground and file-name cells, never a cursor, nothing without decor; lapis's plaques stay inside their tag's band, clear of every grip, only the focused one striped; its checker is in the track; no other theme draws any; the separator and focus tests cover lapis. Goldens: theme and themesel (the ring gains lapis after acme). Gates as G4. Feel review: .scratch/render/lapis/ (lapis.png, lapis-2x.png, tags-focused-vs-unfocused-2x.png, a PanelSlide at 60 fps and a quarter).
* G4: bloom, vignette and grain in the post chainGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three bundled Shadertoy passes beside Crt, each `Bloom|Vignette|Grain 0..3` (off by default, nothing drawn while off), in shaders/post/: - Bloom: what is brighter than the page (a channel's linear peak over 0.75/0.7/0.6 and over the page's own + 0.15, so a light page does not bloom) glows, 2/3.5/5% (§8.2's budget). The glow is a dual Kawase blur in RGBA16F textures at half size and down, 3/4/5 steps by level (shaders/bloom-down, bloom-up; Post.bloomChain), composited in linear light and dithered. - Vignette: round, from halfway to a corner, 10/18/28% at the far corners, in linear light, dithered. - Grain: a still, triangular-spread grain of 1.5/3/5 of 255 on page-coloured pixels only, a logical pixel big; still, so it asks for no frames. Focus rule: the shell passes every bundled pass the rectangles of the tags with their grips, the column and workspace tags, the notices and the cursor (pardesSpare, at most 32, neighbours on one row merged), and a bundled pass leaves them as they are; and a per-theme ceiling (pardesCap, Post.capsOf) keeps the page's text and the selection's text at min(their contrast, 4.5) under each pass at its strongest. User files get no ceiling and no spared rectangles. Fix found on the way: SDL GPU binds at most 4 KiB of a uniform block, so every Shadertoy colour after iPalette (iBackgroundColor, iForegroundColor, the cursor and selection colours, iPalette[>=4]) read zero. The prefix's block is cut in three (Globals, Palette, Colors) with ghostty's names and order, each pushed as a slice of the one struct; pardes's own block moves to binding 3. Tests: the caps hold over every native theme; each uniform slice fits 4 KiB; the prefix's members in ghostty's order across its blocks. Gates: tty/gui unit-test and core-test pass; snap fails only nested-optout; GUI goldens 01-08 byte-identical (09-18 wait on wkzlsqvy, as in somtrmsz); web builds. Feel review material: .scratch/render/{bloom,vignette,grain}/ (levels on forge, dusk, acme, crops, a levels mp4).
* Rules and chrome scale with the display's density; dark pages get visible ↵Gabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | separators and focus tints Density: dp() in gui.zig draws every size given in pixels in logical pixels (SDL's window display scale, rounded, at least one), as acme scales Border, ButtonBorder and Scrollgap: the rules (rule_px), the tag rule, the grip's ring, its dirty gap and mode bars, the rail's gap to the text and its minimum, the thumb's inset, the rim, a bar cursor's minimum width, underline and strikethrough thickness (the atlas is dropped on a scale change), the rule-grab margin, and the Crt's scanline and mask periods (pardesScale in the post prefix). Cell- and tagline-measured sizes stay: the rail's width, Lift's blur and offsets, every motion; iResolution, fragCoord and iMouse stay in the display's pixels, as ghostty's. PARDES_TEST_SCALE forces a density in a harness (a test window is 1x otherwise, whatever display it lands on) and sizes the test font with it. Colours: a separator that stands off its page by less than 1.5:1 is lifted toward the text to 1.6:1 (helix, atelier, paper; a theme with no page, dark, is judged against #121212), and empty_col follows it. forge's own rule already stands at 3.83:1; what hid it was density: 2 device pixels on a 3x screen, now 6 (dp). A focused tag's tint closer than 1.5:1 to the plain tag on a dark page (1.25:1 on a light one) is pushed further the way it leans, as far as its text keeps its own contrast or 4.5: forge 1.23 -> 1.51 (#2d3440 -> #374253), and likewise dusk, orchard, ink, lagoon, clay, harvest, spectrum, solarium, forge_soft; daybreak, atelier, paper to 1.25. dark and helix gain a tint of their own (dark: #484566 under #c8c8c8, 1.54:1; helix: ramp 237 under 250, 1.65:1). Tag caret: past a full row's end, the G3 glide box sits on the tag's right edge, where the layer's caret and the pixel shell's are. Tests: every native theme's separator >= 1.5 and every dark one has a tint >= 1.25 with readable text; forge keeps its own border; the tag caret glide box at a full row; at 2x the spine, tag rule, ring, rail start and gap, and bar cursor double. Legacy-ThemeFile test strips helix's new pair. Goldens: snapshot goldens change in colour rows only, the tints (orchard #283a2f -> #314738 at boot, forge, helix and dark in theme/themesel). GUI goldens: the harness's single Del of the renamed wide pane is refused since ysqnkyoy (a rename counted as unsaved; fixed on the 9P line in wkzlsqvy), so scenes 09-17 were recorded with that pane open and the file was stale since the merge (08 and 18 also moved with ykvnltvs's full-row tag wrap). The goldens here were recorded with that pane closed (as wkzlsqvy will close it); against the parent's binary under the same conditions they differ only in the tints: 01-13 forge's (#2d3440 -> #374253, and the glyph edges on it), 14 ink's; 15-18 are byte-identical. Until wkzlsqvy is merged, a run here fails 09-17. Each commit reproduces its own recorded goldens on this machine (checked at kvtmqkyn). A test window is 1x unless PARDES_TEST_SCALE says otherwise, whatever display it opens on. Prebuilt shaders refreshed from their sources. Captures: .scratch/render/dark-borders/{before,after,compare,scale2,scale3}.
* G3: the focused cursor glides a jump on the Motion flavour's springs, and blinksGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The core owns the motion, as Lift: animation.CursorGlide keeps the focused cursor's four corners on springs (leading corners at the flavour's pace x2.4, trailing ones x follow, so a jump smears and collapses; a long jump bows by the flavour's arc), sampled at each frame's own time. A step of a cell or less, insert mode, a focus change and any scroll (a file's view, a terminal's output) land at once; a snap lands a glide under way too. The quad is clamped to the focused pane when drawn (never its springs). Chrome carries it on the wire (cursor_glide: bit 1 a cursor, bit 0 gliding; cursor_alpha; cursor_quad, grid cells; cursor_idle_ms): the GUI draws the quad as an overlay in the cursor's colour, at 85% (70% on the long flavours) rising to solid as it lands, and hides the cells' cursors while it does: one or the other every frame. Only the focused cursor glides. Blink (CursorBlink, on by default in pixel shells) is the shell's: from cursor_idle_ms and when the frame arrived, solid while typing and 500 ms after, 530 ms halves with 80 ms eased edges, solid after 10 s idle, and never while the window is unfocused or minimized or on a virtual clock. An edge redraws the last frame with no core render (level B, blink_redraws); an attached GUI blinks from the same field without a frame per edge. Tests: snaps a cell, glides a jump with smear and bow, arrives under a pixel by 150 ms on smooth and lands exactly, shifts with a scroll; blink holds, eases, stops; the core glides a jump (ge) frame by frame (gliding exactly while it moves, alpha rising, exact at rest), snaps a step (j) and a switch to insert mid-glide; a terminal's scrolling output lands its cursor; wire round-trip of the cursor record.

* Motion flavours differ by design, and drive notice drops and pane movesGabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The flavours looked alike because Lift, the only motion that read them, moves a shadow a few pixels: overshoot and wind-up were sub-pixel. By design now: crisp leaves at full speed and never passes its mark; smooth (the default) eases in and out in twice crisp's time, a slide arriving in 208 ms (inside §8.1's 220); bouncy passes its mark by ~30% and settles twice; playful winds up, passes by ~40%, and stretches and squashes, text included (the user's choice). Small motions are exaggerated by the flavour's gain. Motion gains launch, gain, span and norm, and ease(u)/speed(u) for moves of fixed length. The notice drop follows ease() over its fall (alpha never behind its position) and stays inside its pane's body past its row. Panel tracks carry the flavour in Track.motion (the old padding byte; macOS header name follows); opening and moving slides, zooms and rises follow it over span x their frames; landed, a pane is exactly its target; closing keeps its own exit. A pane past its mark never takes a neighbour's click; a rising one stays in its box. Tests: each flavour's lift trajectory distinct; flavour character; exact landing bit for bit; a stretched pane's drawn cells map back; the overshoot hit rule; the vertical clip at peak; legacy tests pinned to crisp. GUI golden 18-mid-transition changes (the retuned smooth slide at frame 6).

* acme looks like acme; every theme gets acme's button, scroll column and 2px ↵Gabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rules acme takes plan9port's own colours (acme.c iconinit, draw.h): selections #eeee9e in the body and #9eeeee in the tag, black ink; exec and look sweeps #aa0000 and #006600, white ink; a #99994c scrollbar under a #ffffea thumb; black rules; a #8888cc tag/body rule and column button. Every theme: the grip is acme's button, its tag row's full height, in one scroll column with the scrollbar (rail_px, 12 at a 17px tagline, scaled, times GripWidth, a percent, default 150; same x0/x1 to the pixel): focused clean = solid box; focused dirty = box_dirty filled to a box ring (acme's modbutton); unfocused clean = a box_border ring round the tag's ground; unfocused dirty = box_dirty a pixel inside that ring. The grid, which has no ring, marks dirty with a bold * on box_dirty in the grip's second cell and fills an unfocused grip halfway to its ring. Regions carry a dirty flag. Column buttons are the same shape, solid. 2px rules between columns and stacked panes (inside the tag band's slack), none at the window edge; a 1px tag/body rule halfway between tag and page. Theme data: tag_sel_bg, sweep_bg/fg, tag_rule, rule_px, rail_px, box_border, box_dirty. Chrome: rule_px, tag_rule, rail_px, grip_border, grip_focus_ring; a comptime guard on Chrome's layout forces a wire bump once v8 ships. Structural rules are exempt from the focus-indicator rule (docs/effects.md). Tests: acme widths; stacked rule in the slack at two tagline sizes; every grip-column pixel is band, button, ring or rule, and the button shares the scrollbar's x0/x1 (4 metrics x top/bottom x focus x dirty); the four grip states distinct in every native theme with a non-colour dirty cue in the grid; wire round-trip of the new fields. Shared files: src/colors.zig, src/surface.zig, src/body_layer.zig, src/tagline.zig, src/detached/wire.zig, docs/themes.md, docs/config.md, docs/effects.md, 21 snapshot goldens (the grip cells only), test/gui-goldens.txt. Motion flavours differ by design, and drive notice drops and pane moves
* Motion flavours, and Lift is shadow, rim or auto: auto on a dark page ↵Gabriel Schneider27 hours
| | | | | | | | | | | | | | | | | | | | recedes the other panes (InactiveDim) Motion off|crisp|smooth|bouncy|playful is one parameter set (animation.Motion) every fx animation reads. One focus spring per pane drives both the lift and the dim, at the flavour's pace; a grid snaps. Lift drops glow and surface. A shadow falls on pane bodies and rails only, capped so text and the selection keep min(contrast, 4.5); rim is a hairline along the focused tag's top. auto is a shadow on a light page; on a dark page the core recedes the unfocused panes' text (InactiveDim, ported from 2e4d97f, default 30 under auto) with the same floor. Tests: focused text contrast is never below unfocused in any style, dim or theme; the focused pane's cells and tag are untouched by a dim.

* G1: Lift, soft elevation shadows (off by default)Gabriel Schneider27 hours
`Lift` (a GUI toggle, capability lift) lifts the focused pane on a critically damped spring (animation.Spring: closed form, about 240 ms to settle, velocity kept across retargets, settled = no frames) and floats notices. The core puts the lift on the regions (Region.lift, on the wire); the GUI casts from it: a soft shadow is decor, an erf rectangle on one quad grown by 3 sigma (decor.frag, flag 0x10000000), in the quad's own space so a track's transform carries it; darken-only, the caster's rect left alone, alpha pre-warped for linear light and IGN-dithered. Cast last in its group, so a neighbour's rails and rules darken with its text; a notice's before its rule. Strength is capped per theme so text over the darkest shadow keeps min(its contrast, 4.5) (test over the native themes). Opt-in until the focus lift/dim default is decided. Feel review material: docs/effects.md. Test-mode PARDES_TEST_SERIES keeps every captured frame. Shared files touched: pardes.zig (two fields, one nextWake line), detached/wire.zig (lift on the region), config.zig, builtins.zig (capability), gui.zig. Not touched: Messages.zig, mouse.zig, tty, host_io.
