Artwork Dynamic currently computes colours during focus changes, averages unrelated artwork hues, and animates the root theme while replacing its expressive tokens. This makes browsing do avoidable work and can produce muddy colours.

Successful Coil image loads now queue background palette extraction from the decoded bitmap. A 96×96 sample feeds AndroidX Palette; Aperture ranks populated, saturated swatches and ignores transparent pixels, near-black/white and near-grey candidates. Hardware bitmaps use a small software sample without recycling the displayed image. At most two extractions run concurrently, and requests for the same artwork coalesce.

Room stores the selected seed by artwork path and extraction version. Database migration 7→8 adds the palette table while retaining the existing library and playback tables. Focus changes only observe the table after a 140 ms settle delay: they do not download or decode artwork. A pending row updates the theme as soon as extraction saves it. Metadata/artwork changes select the current path automatically; renaming without changing artwork reuses its palette. Cinematic Ambient uses the same store and can prefetch a missing next backdrop using the renderer's URL.

Browsing and cinematic logos share Material tonal colour roles. Dynamic primary, secondary and tertiary roles are opaque, with paired foreground/container colours. The secondary source has reduced saturation and the tertiary source shifts hue by 60 degrees; these are Aperture palette choices. Theme colours fade with the existing fast Material Expressive effects spring. The token object and semantic colour scheme stay stable throughout the fade, so unchanged spacing, shape and motion consumers are not invalidated every frame. Named themes and the approved Material TV logo palette remain available.

Validation on 709ba94:

• Standard debug APK assembly passed.
• All 28 standard debug unit tests passed, including focus debounce, metadata replacement, pending table-row arrival, unchanged-artwork reuse and cancellation.
• All 10 instrumentation tests passed on Television_1080p, Android 16. These cover represented-hue selection, transparency and monochrome fallback, hardware bitmap ownership, persistent reuse, extraction-version invalidation, library-preserving migration, one display fetch with no second palette request, and a real intermediate fade colour with stable tokens and no per-frame recomposition of unrelated content.
• Instrumentation used a temporary application ID through an uncommitted Gradle init script to preserve the emulator's differently signed Aperture installation. Temporary test packages were removed.
• git diff --check passed.

Physical-TV frame-time profiling and subjective review against a real media library remain outstanding. No measured FPS or speedup is claimed.
