OUT-2: WebM export (VP9 intra encoder + alpha, Opus), WAV/AIFF audio-only outputs
- effectcraft-vp9enc (L0): VP9 profile 0 key-frame encoder from the VP9 bitstream spec
(8x8 intra blocks, DC/V/H/TM, 4x4 DCT/ADST, lossless WHT at quality 100, tile columns);
round-trips exactly through FilmCraft's VP9 decoder and ffmpeg.
- export: WebM muxer (EBML/Matroska spec) with VP9, VP9 alpha in BlockAdditional
(AlphaMode 1), Opus (CodecDelay = pre-skip); WAV and AIFF outputs.
- OutputFormat WebM/Wav/Aiff in the Render Queue, renderQueue.add formats, CLI --format.
- Tests: FilmCraft decode-back (frames, size, pixels, audio RMS), ffprobe/ffmpeg oracles.

IO-2/SHP-5/PRV-2: PSD import, SVG import + vector/text conversions, persistent disk cache
- effectcraft-psd (L1): PSD/PSB reader from Adobe's published file format spec (layers, groups,
masks, blend modes, text engine data, lfx2 effects, fill/adjustment layers, vector masks;
1/8/16/32-bit, RGB/CMYK/Gray/Lab/Indexed, raw/RLE/ZIP) and a minimal writer for fixtures.
- File > Import: importAs footage|composition|compositionLayerSizes, layer (Choose Layer);
groups -> precomps (pass-through collapses), text -> editable text, styles -> Layer Styles,
adjustments -> adjustment layers with effects; UI asks the Import Kind for Photoshop files.
- effectcraft-svg (L2): SVG parser (shapes, paths, transforms, use, CSS, gradients) and
rasteriser; .svg imports as footage, continuously rasterised when the switch is on.
- layer.create: shapesFromVector, shapesFromText, masksFromText, editableText (stub removed).
- Disk cache (render::disk_cache): LZ4 content-keyed frames and layer buffers, LRU size limit
from prefs, atomic writes, restart persistence; edit.purge clears it, cache.diskStats query;
viewer frames read/write it and the timeline shows disk-only frames in blue.
