bflatastic 26c714db7f M4.14: content-keyed RAM preview frames; proxies in the disk cache's content key 
- FrameKey's identity is the comp's content (frames::comp_content), not the project revision:
  an edit keeps the cached frames of comps it doesn't touch and undo finds the frames of the
  state it returns to. The identity hashes the addresses of the comps a comp draws (~0.1 ms on
  the 1500-layer test project; the full content hash took ~117 ms), by value the footage, solids,
  proxies and project settings; with expressions, every item. Frames::content_of keeps a
  project snapshot per identity with frames (or in flight), so Arc::make_mut always copies an
  edited comp and its address can't be reused meanwhile; past 64 identities the least recently
  used go with their frames (long drags).
- drop_stale is gone (frames of other contents are evicted least-recently-shown first).
- disk_cache::comp_content_key covers items' proxies and Use Proxy (it served stale frames).
- Tests: frames (content keys, edits elsewhere and undo, bounded drags, in-place edit safety),
  ui_ram_preview (end to end), the disk cache proxy key. Docs: roadmap (M4 done), parity.

Brandon Thomas 94e1c86d89 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.
