A frame whose last byte happened to match the superframe marker pattern
(0b110xxxxx, Annex B) was taken by decoders for a superframe with an
index at its end: ffmpeg rejected it ("Invalid le value at
frame_sizes[i]"), libvpx reported a corrupt frame, and later frames lost
their reference. In the reported WebM, 3 of 60 frames (10, 22, 24) ended
in 0xc8, 0xc0 and 0xca. The render still reported success.
Such frames now get a zero byte after the last tile; the last tile's
bool-coded data may end in zero padding (9.2.3).
Test: frames_never_end_in_a_superframe_marker encodes sequences until a
frame needs the padding, checks no frame ends in a marker byte, and that
the padded frames decode exactly with FilmCraft's decoder and with
ffmpeg (clean error log). It failed before ("96x64 q40 frame 22 ends in
0xde"). The ffmpeg IVF oracle is shared with the existing inter test.
Checked with the reporter's steps: 60/60 frames, no errors from ffmpeg's
vp9 or libvpx, RGB and RGB + Alpha.

Render Settings: field render with 3:2 pulldown phases, effects/solo/guide
layer/color depth/frame blending/motion blur overrides, custom time sampling
(duration), storage overflow through a quota hook. Output Module: crop
(edges or region of interest), resize (presets, lock aspect, quality),
straight/premultiplied/alpha-only channels, post-render actions, include
project link, audio channels and PCM formats, WebM bitrate and key frame
interval. Render Settings / Output Module templates with built-ins and
defaults per slot (Edit > Templates dialogs), render logs next to the
output, Notify on completion. All through renderQueue.* commands and
persisted in the project.

effectcraft-vp9enc gains inter frames: single LAST reference, 16x16/8x8 blocks,
candidate + diamond search refined to quarter samples with the regular 8-tap
filters, NEARESTMV/NEARMV/ZEROMV/NEWMV with spec MV prediction, skip blocks,
the in-loop deblocking filter, per-frame forward probability updates, a key
frame interval and target-bitrate rate control. Decoded output matches the
encoder's reconstruction exactly through FilmCraft's decoder and ffmpeg.
WebM export now encodes sequentially with a key frame every two seconds.

New L0 crate effectcraft-opusenc: clean-room RFC 6716 CELT-only encoder
(fullband 48 kHz, 20 ms packets, mono/stereo as dual L/R stereo, constant
packet size from the bitrate) with the RFC 7845 OpusHead and pre-skip.
Forward low-overlap MDCT, inter/intra coarse energy, fine/final energy,
the decoder's exact allocation, recursive band splitting, PVQ search and
codeword indexing, silence frames.
crates/export depends on it; filmcraft-opus (dev) is the round-trip oracle
in tests/opus_roundtrip.rs, with ffmpeg reading an in-test Ogg Opus file
as a second oracle when installed.

New L3 crate effectcraft-gpu: a wgpu compute backend for the per-frame
compositing walk (layer transforms with the CPU's nearest/bilinear/bicubic
sampling and minification pre-filter, motion-blur accumulation, track
mattes, Preserve Transparency, layer style passes and knockout, all 38
blend modes as a WGSL port of color::blend, 8/16 bpc clamp+quantise,
colour-space conversions). 3D runs, adjustment and wireframe layers run on
the CPU between GPU steps. GPU effects with the CPU semantics: Gaussian,
Fast Box and Directional Blur, Glow, Levels, Curves, Hue/Saturation, Tint,
Fill, Gradient Ramp, Fractal Noise, Drop Shadow, Brightness & Contrast,
Exposure, Invert, Transform (registry gpu badge from effects::GPU_EFFECTS).
render: Backend (Cpu/Gpu/Auto) in RenderOpts, the Accelerator trait and
Renderer::accel, GPU effect chains in the effect stack, hooks for the GPU
walk. Project setting gpu_acceleration (Mercury GPU Acceleration / Software
Only), render.backend command, file.projectSettings renderer. Session and
Render Queue exports carry the accelerator. CLI --gpu and bench --gpu.
Tests compare GPU vs CPU renders (blend modes x bit depths, transforms,
masks, mattes, motion blur, colour management, styles, collapse,
adjustment fallback, every GPU effect) and skip without an adapter.

- apps/effectcraft-web (L6): eframe web runner booting the shared EffectcraftApp with a browser
session: in-memory file table, <input type=file> pickers and drag-and-drop for open/import,
downloads for Save and Render Queue outputs (several files as one stored .zip), and the
window.effectcraft promise API over the control channel. Demo project on start.
- wasm32 runtime fixes: web-time for Instant/SystemTime (render, engine, export, ui-egui);
Frames renders queued jobs on the UI thread (Frames::pump) instead of a thread pool;
Render Queue runs inline; relative outputs resolve under / ; control PNGs inline.
- effectcraft-export: per-job output Sink (files to memory instead of disk); host FileExporter
carries it; test that sink exports touch no file.
- xtask web [--dev] [--serve PORT] (wasm-bindgen 0.2.129, optional wasm-opt, COOP/COEP server);
effectcraft-web in WEB_CRATES. docs/web.md, headless Chrome smoke test, favicon (+attribution).
