Replaced the sparse-noise-specks static effect with a jagged horizontal
glitch band (plus scattered specks), still procedurally generated with
Pillow -- no source footage involved. Tried deriving this look from a
real, explicitly free-to-use "VHS glitch" stock clip first, but dropped
that approach: even downsampled to 32x32 and thresholded for
transparency, recognizable footage content showed through at any opacity
that read as an actual band rather than noise, and it compressed
noticeably worse than procedural noise. Verified payload stays well
under the 460KB limit against the live station.
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.
