Shows a brief static effect (sparse noise specks, bundled as a small
animated GIF) over the album art during the first/last 5 seconds of a
track, as a transition cue. Implemented via render.Stack compositing a
bundled images/static.gif over the zoomed art -- pixlet has no per-frame
procedural drawing hook, so the noise is pre-baked with Pillow rather
than generated at render time; render.Image plays animated GIFs back
natively, independent of the zoom's own animation timeline.
Tuned the GIF's frame count/density/flicker speed down after an initial
version pushed total payload within a few percent of the 460KB device
limit on some album art -- more, faster-changing frames give WebP less
opportunity to dedupe near-identical frames, which compounds with the
zoom animation's own dedupe needs. Final version adds ~50KB regardless of
art complexity, verified via a pinned-cover test harness for reliable
before/after comparison (the live station's currently-playing track kept
changing between test runs otherwise).
Added a "Static overlay" On/Off schema toggle (default On) per request.
