Cumulative candidate on top of origin/main (7ae47d5).
Slices 1-5: compact-model image records, vendored decode-only libwebp,
wire contract + loader state machine, owner-loop /media dispatch with
retained page-Link reuse, screen render with bounded PSRAM LRU pixel store.
Local checkpoint only — not pushed.
