* G5: lapis, 0x4200.cafe's manuscript, as a theme with its ornamentGabriel Schneider29 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.

* G4: bloom, vignette and grain in the post chainGabriel Schneider29 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 Schneider29 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.

* G3: the focused cursor glides a jump on the Motion flavour's springs, and blinksGabriel Schneider29 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 Schneider29 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 Schneider29 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.

* Motion flavours, and Lift is shadow, rim or auto: auto on a dark page ↵Gabriel Schneider29 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 Schneider29 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.
