OK runs layer.newPrimitive, which switches a Classic 3D comp to Advanced 3D in the same undo step. The dimension fields are the Geometry Options the engine builds for the chosen type.
The dialog offered four hard-coded light types and reopened an Environment light as Spot, so OK turned it into one. It now lists every light type the engine has, keeps the light's own type, and shows Falloff and Shadows only for lights that have them.
- `Frames::disk_frames` takes a frame range instead of a frame count, still clamped to the existing 100,000-frame limit.
- The Timeline passes the visible range (`disk_bar_range`), including frames only partly in view, and clips the blue bar to the work-area row.
- Membership stays live: nothing is cached, so the bar updates as before when frames are written, evicted or promoted to RAM.

`crates/ui-egui/src/frames.rs`:
- The cache remembers the scale of the frame on screen (the active viewer's urgent request). Prefetch and passive viewers don't change it, so a second viewer at another zoom can't evict the active viewer's frames.
- RAM and GPU eviction take frames of other scales first, then fall back to the existing playhead-aware order.

Both devices EffectCraft creates now ask for `MemoryHints::MemoryUsage`:
- the window device (`apps/effectcraft/src/main.rs`, through a new `device_descriptor` helper);
- the headless compositor device (`crates/gpu/src/context.rs`).
The limits, labels, features and error paths are unchanged. The devices tests create stay as they were.

- New `crates/project/src/file_check.rs`: a no-output `Serializer` that walks the value once. It refuses non-finite numbers and nesting past 127 levels, and it allocates only on error.
- `to_file_json_with_view` runs that check, then writes the file. It also refuses a project schema newer than this build, the remaining thing `from_json` would reject in a file we wrote.
- **Debug builds still reparse the text as well**, so a new kind of mismatch still shows up in tests.
The bytes written are unchanged.

`crates/effects/src/noise3.rs` only:
- a `blend_mode(u32) -> Option<BlendMode>` helper, which the CPU and GPU paths now share;
- the CPU `render` resolves the mode once and passes `Option<BlendMode>` to the per-pixel `composite`.
The semantics are unchanged: None means the noise alone, and an unknown index means Normal.

The gradient antialias could leave a half-covered pixel where an opaque source reaches h = 1. Add an endpoint guard on CPU and GPU and cover an opaque edge in the regression test.
Use the measured Softness kernel (sigma = 0.42 * Softness), threshold the blurred height with a ~1 px antialias, and allow Cut Away 100 to empty the matte. Split the source-matte displacement from the height-field RGB refraction: the matte uses a z=1 bevel normal fitted to the T2 step edges, while RGB follows the measured z=height refraction. Align the documented AE defaults and add CPU regression tests for the cut threshold, Cut Away 100, and the inward matte warp. Update the GPU kernel and parameters to match, keeping CPU/GPU parity.
- English (and Auto where offered) stays first as the source language and fallback; the rest sort by native name with accents folded, so Čeština is under C and Magyar under M; Cyrillic and CJK names follow the Latin ones
- The list used the registry order, which is the order the languages were added
On an adjustment layer Motion Tile kept the comp-sized buffer whatever the
Output Width / Height, and the adjustment draw dropped any stack result whose
size differed from the canvas. After Effects grows (or crops) the comp
rectangle there as on any layer, so a Transform after it brings the extra
tiles into view, as in the frames attached to #1727 and #1409.
- motion_tile_frame: one output frame for the CPU and GPU effect; on an
adjustment it grows about the comp rectangle on whole pixels, keeps the
buffer at 100 % and past 16 384 pixels a side.
- adjustment_crop: the CPU and GPU adjustment draws put a stack result whose
frame changed back onto the canvas instead of dropping it (Enc::crop on
the GPU).
Tests: the #1727 After Effects frames (910 x 340 % and 90 x 340 % then
Scale 12 %), tiles past the frame and cropping on CPU, GPU vs CPU for
adjustment and full-frame layers.

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.

Session::bump took the disk cache's footage salt at every edit, which reads the size and time of
every footage file, each frame of an image sequence included. With three 5000-frame sequences a
caret move or a typed character in a text field took ~0.6 s on the UI thread (9 ms with the disk
cache off). The salt is now taken again only when the footage items changed, or when a project
is opened, footage is reloaded or the disk cache attached.

Review: styled() kept the buffers it rendered instead of the ones LayerCache::insert returned, so
without a blending-space conversion concurrent misses still returned separate body and pass
buffers (and the GPU uploaded each).

Alt/Option-drag a Project item onto a Timeline layer, or press Ctrl+Alt+/ (Cmd+Opt+/) with layers and an item selected, to swap the layer's source. The layer keeps its name, timing, transforms, keyframes, expressions, effects, masks, switches, parenting and track matte; a source with audio adds Audio properties when missing. Precompositions can't be nested inside themselves.
AVLayer.replaceSource now runs the same engine command and closes the replaceSource part of #813.
Preview workers that start together miss the layer cache together, and each kept its own copy
of every layer; on the GPU each copy was uploaded and packed into its own Classic 3D atlas, which
ran the device out of memory on a cold start. LayerCache::insert now keeps the first buffer of a
key and returns it, and the renderer goes on with the returned buffer, so the workers share one.
Renders don't wait for each other: on the shared frame pool a blocking wait could end up beneath
the work it waits for (tried, it stalled playback for the wait's timeout).

Looking up to the whole RAM preview for uncached frames let the workers spread over the preview
while the playhead waited. On the GPU each worker then built a Classic 3D atlas for its own set
of layers, and on a cold start of the #1812 project the device ran out of memory far more often
(first pass 1-56 % of real time instead of 63-81 %). The window now keeps its old width but
starts at the first frame ahead that isn't cached, so a loop or a restart still renders on at
once.

Review: two footage items of one file with different nominal sizes could share a sized entry,
though one is resampled and the other kept as decoded.

Review: mask motion blur draws an animated mask at the shutter's other times, but the layer key
hashed its value at this time only. Two frames with the same mask value (a hold before a move)
shared a cached layer, with the wrong blur. This applied to solids, text and shapes already, and
to stills since this PR.

Review: still_at_size returned a smart object's pixels unresampled when they differed from the
footage's nominal size. It now follows footage_buf: pixels larger than nominal are resampled to
the requested size, smaller ones are left for the renderer to scale up.

The Index-units test now opens the Units popup in the Timeline and picks
Index, asserts the stored Units value, then reads the painted Start, End
and Offset, so it also fails when the Units control doesn't update the
session.
Review: frame_at_size at a still's native size made a second cache key, so the pool decoded
and kept a second full-size copy of a frame thumbnail() or frame() already had.

The playback prefetch only looked ahead*3 frames (96 with 16 workers) for uncached frames.
After a loop or a restart from the start those were all cached, so the workers stood idle until
the playhead came within that window of the end of the cached run, then the preview stalled.
A playing preview now looks as far ahead as the RAM preview holds (and the range spans) for
the next uncached frames, still queuing at most ahead at a time; eviction already spares the
frames the playhead reaches first (#595).

Footage layers had no layer cache key, so a still made a new layer buffer every frame on every
preview worker, and the GPU compositor uploaded it again each time (its upload cache is keyed
by buffer). Stills (without a proxy) are now keyed like text and shape layers, without the
source time; movies and sequences are unchanged.

The media pool honoured the requested size only for movies; stills came back
at full size and the renderer resampled them on every frame. A 21120 px wide
plate at Quarter was re-filtered each frame, and four of them (1.85 GB as f32)
did not fit the 1 GiB pool, so they were also decoded again and again.
Stills are now resampled once with effectcraft_raster::resample (the same
call the renderer made, so pixels are unchanged) and the pool keeps the
reduced copy under the sized key.
#1812 project at Quarter, CLI bench: 410 ms -> 33 ms a frame (26 ms with the
layer cache); desktop playback 2% -> 60-99% of real time.

Illustrator EPS imported as an empty layer. Three gaps in the PostScript
interpreter, each against the PostScript Language Reference:
- An operator stored under another name (`/mo /moveto load def`, as
Illustrator's prolog does for every path and paint operator) pushed the
operator's name instead of running it, so nothing was drawn.
- Device queries that return values (currentpagedevice, currentscreen,
currentflat, currenthalftone, status, dictstack, ...) pushed nothing,
shifting the stack under the procset's guards. They now push a plain
device's defaults; setscreen pops its three operands.
- `currentfile 0 (eod) /SubFileDecode filter` now skips to the end-of-data
string, so an embedded XMP packet isn't run as PostScript.
The regression test uses synthetic PostScript only.

WGSL cannot read Rust constants, so the Rec. 601 luma (Tint, Tritone, Luma Key /
Extract), Black & White's tint weights and Exposure's 2.2 power stay literals in the
kernels; they now name their Rust source (effects::LUMA_601, BW_TINT_LUMA,
EXPOSURE_LINEAR_GAMMA, newly exported) and the test shader_constants_match_the_cpu
(no GPU needed) fails if a literal drifts. gpu_tint_defaults_match_after_effects_greys
says "skipped: no GPU adapter" when it skips (EFFECTCRAFT_REQUIRE_GPU=1 still makes it
fail). docs/effects-parity.md: Brightness & Contrast is close to, not the same as,
After Effects (up to 6.2/255), and the summary row lists what is measured.
