let the GUI rest; a perf gate
somtrmsz's contrast floors made ChromeTheme.fromTheme run its focus-tint
and separator searches (pow calls each), and Output's RowDecoration.styleAt
called it for every grapheme of every highlighted row: the 50k-line file's
render went from 0.11 ms to 13 ms. Pardes.bodyChrome now keeps the theme's
chrome, worked out again only when the theme differs; recolorSyntax asks
for it once a decorated row, and a plain row (nearly every row of a file)
never asks. ReleaseFast, medium fixture, median us, before -> after (main):
render 13150 -> 76 (111), key-down 14658 -> 79 (110), wheel 13589 -> 76
(109), open 14891 -> 2095 (2055), edit-char 16703 -> 3006 (1251; the rest of
that gap is editing and tree-sitter, not this).
Post.animating asked for frames whenever the window had focus and any pass
was ready, so a still pass kept the GUI drawing at the display's rate
(Bloom: 49% of a core idle, in a hidden test window). A pass now says
whether it moves on its own: the CRT (its hum and dither) and a Shadertoy
file whose source reads iTime, iFrame or iDate (shader_build.readsTime; the
flag rides the wire's post message); Bloom, Vignette and Grain are still.
Bloom idle: 49% -> 1.2%, as with no pass.
zig build perf-gate: the 50k-line file's gestures, each's fastest sample
within 3x of the recorded baseline's (test/perf-baseline-<platform>-
<optimize>.json, recorded from this build), run with every unit-test. On
the regressed code it fails at 180x for render.

deleted, reloaded
get on a file gone from disk failed with a bare ENOENT; it now says get:
<path>: no such file. A watched file deleted on disk was silent; the pane
keeps its text and says <file> deleted on disk (Save writes it again)
once, logged changed <serial> deleted (only a path the watch has read: a
pane renamed to a name never on disk is not deleted). A get that throws a
dirty buffer's
state away logs changed <serial> reloaded, as the watch's reload does.

choices, a clean reload is logged
get's refusal now quotes the line as a builtin's (Save's) does; a bare
answer while a question stands says what it takes (answer takes k j or
-); and a clean buffer reloaded from disk logs changed <serial> reloaded,
as the kept dirty case logs changed <serial>. (A failed Save already says
why: Save <path>: <the error in words>.)

A watched file rewritten on disk was loaded over a buffer's unsaved edits
and its dirty flag cleared, so Exit and Del no longer asked about them. A
clean buffer still reloads; one with edits keeps its text and stays dirty,
says <file> changed on disk (get reloads it, Save overwrites it), logs
changed <serial>, and its Save warns once before overwriting the newer
file, as acme's Put refuses a file modified since read (exec.c:577); get
asks as ever (winclean, exec.c:513). The restored-watch test's dirty case
now keeps the snapshot, and the filewatch snapshot script (re-recorded
by name) checks both halves: the edited pane keeps its edit and says so,
the clean one reloads.

Exit, Restore, Del and get warn only about a pane edited since it was
opened, which its saved hash says (set at its first edit). A pane a Dump
kept dirty came back with no hash, so a restored session quit at once
over it. Restoring one dirty now gives it a hash its text does not match.

A restored text pane came back with its caret at its view's top, whatever
had been selected. The dump now keeps each text pane's dot, q0 and q1 as
acme's keeps a window's, and Restore puts it back without moving the view
it kept. Two look-walk tests that restored and walked on now start from the
match they were on.

dirty compared revisions only, so undoing to the save point, or typing the text back, left the pane dirty. The saved text's hash is kept from the first edit after a save or load, and an edit that makes the text equal to it marks the pane saved again, as undo to the save point does in acme.

The painters of a pane's body and tag (renderBody and its selection,
gutter, syntax, ANSI and wrap-marker passes; paintPaneTag; paintHeaders;
renderPane; the image and PDF grid paths) take the Surface they paint as a
parameter. The body layer and the tag layers paint straight into their own
temporary surfaces, and the std.mem.swap of p.surface around those calls is
gone. No behaviour change.

helix's expand/shrink, previous/next sibling, all siblings, all children and
parent-node end/start (Alt-o/up, Alt-i/down, Alt-p/left, Alt-right, Alt-a,
Alt-I, Alt-e, Alt-b; Alt-n stays the new terminal) walk a whole-file parse
the file keeps (File.node_tree), made on the first such key after an edit and
reused until the next, never per key. syntax.walkNodes follows helix's
TreeCursor over every node, anonymous ones included, and Alt-i goes back to
what Alt-o grew from while the selection still holds it. The harness runs
without grammars, so the cases prove the plain-text no-op; a test replays
eleven JSON walks whose results were taken from the installed hx.

language's files
Repl python in a terminal's tag or on its ctl binds it (Repl - unbinds, Repl
bare says the binding, the same word again changes nothing), with an id,
python-a, python-b, in its tag. An exec made by a gesture on the body of a
file in that language -- a middle click or the execute key, on any text, a
single word too -- or on the REPL's own body is typed into it, bracketed if
its program asked for that, else line by line with a once-said warning for
Python's blank lines, then Enter; the message row says -> python-a in the
tag's name tint, the log send <from> <to> <id>. Several bound for the
language: the pane asks which on its notice band, as Del asks, one key
answering, Esc none, nothing remembered. The gesture is known where it is
dispatched (mouse.zig, the execute key), so the tag's words, Exec <text> run
by name and a command word @`cmd` stay commands, and a 9P exec is never
sent. A finished command pane is no REPL; bindings are not dumped. The docs
spell out the escapes, the pdb and input() caveat and the no-bracketed-paste
papercut.

A column's or the workspace's tag has no pane, and asking one for it hit
unreachable; every caller guarded against that by checking `what` first.
An optional makes each caller say what it does without a pane, so a
forgotten guard no longer compiles into a crash.

A tag that is a text can hold a newline, and the tagline, the body under it
and the pointer all assumed one row. The pane's tag now takes a row per line
(up to eight, and never the body's last row); the body starts below it, the
rows a pointer counts start the body after the tag's lines, a click on any
line puts the tag's cursor there, and a pixel shell gets a tag layer per
line. A tag of one line draws exactly as before.

The headers had their own one-line editor with its own keys: Enter always
executed, h/l and J/K moved between headers and panes, Ctrl-c/x/v cut and
pasted, and TagLine refused a newline that 9P accepted. They are now Texts
like a pane's tag, with no prefix and a default until edited, so normal and
insert mode, undo and the look and execute keys are the body's. Moving
between them is the window keys' job: Up from a pane with nothing above it
reaches its column's tag and then the workspace's, Down comes back, and
Left and Right walk the column tags.

The tag was a fixed buffer with its own one-line editor, a cursor measured
across the path, and a hijack of the body's mode while it was typed into.
It is now the pane's second Text: its own characters after the computed
prefix (path, dirty marker, PDF page), which is never stored in it, so a
rename or a dirty marker never moves its cursor. Normal and insert mode are
the body's, undo included; `:` moves the keyboard between body and tag, the
tag remembers its cursor and starts on Save, and executing a word from it
hands the keyboard back. The mouse still sees the prefix: a sweep selects
across it and a click on the path drafts a new name.

A search, pipe or Save prompt wrote its marker and answer onto the end of
the tag, so the tag's cursor, its selection, its 9P writes and a prompt
abandoned by a click all shared one buffer: the abandoned text stayed in
the tag and a 9P write landed inside the prompt. The answer is now its own
Text on the pane, typed in insert mode and shown on the notice band where
it was already drawn, and the tag never holds any of it.

acme keeps what edits a text in its Text (dat.h:171-190) and the window
holds a body and a tag of that type. The cursor, the selections, the modal
state and the edit-buffer undo move off Pane into Text.zig, Pane holds
them as its body, and the edit and normal-mode operations take the Text
they edit. Nothing changes in behaviour; this is the step that lets the
tag become a second Text.

Pure move: the body of `pub const File = struct { ... }` is now the file
File.zig, dedented, with the imports it uses; panes.zig keeps
`pub const File = @import("File.zig");`, so `panes.File.x` callers and the
`File.State` field of Pane are unchanged. File.zig joins the embedded
source list.
