v0.6.89...v0.6.90

Asset bucket for on-demand model downloads — not a software release.

Consumed by skills/embedded-captions/scripts/matte.cjs (sha256-pinned, cached in ~/.cache/hyperframes/matting/). Same pattern as the CLI's background-removal manager pulling u2net from rembg's release bucket. Do not delete: existing installs download from this URL.

HyperFrames v0.6.89

Fixes audio dropout during playback (WebAudio source cleanup), muted video audio leak in renders, IEEE 754 frame-index precision, and keyframe editing stability.

Fixes

• Runtime: Preserve authored muted attr; clean up WebAudio on end (036b991c, #1319)
• Studio: Keyframe bug fixes — gate delete hooks, fix value corruption, gesture recording (f0b499b5, #1314)
• Engine: Add epsilon to frame index floor to prevent IEEE 754 boundary duplicates (3a72aa52, #1318)
