Conflict in crates/text/src/layout.rs (line metrics): main's partition_point
slice from #2193 plus this branch's first-baseline maximum. rustfmt applied to
main's paragraph() signature.

- scriptui.js: replace the self-comparison NaN check (o.max === o.max) with
the explicit Number.isNaN(o.max) (S1764).
- sw.js: mark the fire-and-forget cache.put() with void and a .catch() so the
promise rejection is handled (S9383).
- prelude.js: return __err(...) from the activeCamera getter so every path
yields a value (S4275); __err always throws, so behavior is unchanged.

A 2-D point property took any array: `[1, 2, 3]` and `[1, 2, 3, 4]` were cut to `[1, 2]` and
`[1]` was broadcast to `[1, 1]`, each reported as success, so a script holding a wrong value
silently did something else instead of failing. After Effects raises "Array is not of the
correct dimension" and leaves the property unchanged.
The length must now match the property's dimension, with the one exception After Effects also
makes: two values for a 3-D property, where z stays 0, so `position.setValue([x, y])` keeps
working.

- first_ascent: a "d" shorter than 0.3 x the font ascent (a symbol or icon font) no
longer puts box text's first baseline almost at the box top; the font ascent is used,
as before the "d" rule (CodeRabbit on #1875). Test:
a_short_d_falls_back_to_the_font_ascent.
- CharXf::track_before / track_after are pixels, not 1/1000 em (CodeRabbit).
- The Lottie export of style-run tracking is back to what it was: the pixel conversion
was not checked against a player, so it is left for a separate, verified change.
- The Subtract clamp in Mode::combine is intended for every animator property: the
selectors combine into one selection per character for the whole animator, as in
After Effects; the read-back observed it through Tracking (now said in the code).
- Per-character 3D rotation notes that #1876 adds Mat4::rotation_xyz for the same order.

With per-character 3D on, After Effects turns each character by Rx * Ry * Rz
(Z first), as it turns a 3D layer's X / Y / Z Rotation (case 931, AE 2026:
"H" at 400 px with animator X / Y / Z Rotation 40 / 30 / 20). EffectCraft
composed Rz * Ry * Rx, so the glyph faced another way: 23 of 5184 grid
points off (max 255), now 3 at the anti-aliased edge (mean 0.015/255). The
same order fix-orientation uses for layers; texts with one rotation axis
are unchanged.

A text animator's Tracking Amount is in pixels in After Effects 2026, not in
1/1000 em like the Character panel's tracking: Amount 30 on every character
adds 30 px between neighbours (half before, half after each) at 80 px and at
40 px. And a Subtract range selector over characters the first selector
leaves out keeps them at 0 instead of selecting them negatively. With both,
the EXPORTER's t8 layer D (Tracking 30 on characters 2-4 by index, Subtract
over the last 20 %) puts every glyph where AE does (it ended 88 px short,
1553 vs 1641; now 1641).
The "Tracking In" text preset animates 40 -> 0 px (was 400 -> 0 thousandths
of an em, about the same at 100 px text); Lottie export writes a style run's
tracking (1/1000 em) as pixels for its tracking animator, which Lottie
players add in pixels.

After Effects 2026 lays out right-to-left point text whose paragraph carries a
justified code (justify last left / centre / right, justify all) flush at
its start, the right, like right-aligned text (EXPORTER read-back t7: point
rows with codes 3-6 at -152..-8 from the anchor). EffectCraft placed it by
the last-line side (left / centre / left). Left-to-right point text and box
text are unchanged; AE's slightly wider right-to-left box wrapping (1-2 px
narrower word gaps) stays open.

With Justify All After Effects stretches the paragraph's last line too, and
its every-line composer breaks the paragraph so that line is not a lone
word: a 400 px box that the other justifications break into 6 / 6 / 1 words
breaks 4 / 4 / 4 (AE 2026, EXPORTER read-back t6). EffectCraft's composer
left the last line's slack out of its cost, so "twelve" stood alone on a
stretched line; it now counts that slack for Justify All and every word
starts within 1 px of AE's (what remains in that box is the known box-text
baseline offset). Other justifications and the single-line composer are
unchanged.

After Effects puts the first baseline of paragraph (box) text the height of the
font's lowercase "d" (in whole thousandths of an em) below the box top, at the
text's nominal size; superscript keeps the line there and only raises its glyphs.
EffectCraft used the font ascent of the drawn size plus the superscript rise.
Measured in AE 2026 (case 818, box at y -200): Times New Roman 100 px -130.50
(EffectCraft -110.9), 50 px -165.25, superscript -163.80 (EffectCraft drew it
15.8 px lower), Arial 100 px -128.40, superscript -161.70; now within 0.15 px.
517 (four wrapped lines, Times New Roman superscript): the line bands now land
on AE's rows exactly (336-388, 434-486, 532-584, 643-682; were 16 px lower).
A face without a "d" outline, and vertical type (not measured), keep the font
ascent. The paragraph-box test now
expects the caret (full ascent) to start a little above the box.

Tests that share a fixture each generate it on a first run and rename
their temp file into place. On Windows the losing rename fails with
PermissionDenied while the winner has the file open. Treat a failed
rename as "another test made it first" when the fixture exists, as
`png_sequence` already does.

`Stills` is only used by the `#[cfg(unix)]` part of
`footage_on_other_computers_is_never_looked_at`. On Windows it was dead
code, so `cargo xtask ci` stopped at clippy (`-D warnings`).
