Right panel now shows connection+detection status on one line, small start/stop buttons on one line, event text with the red-note inline, and a 3x3 reverse-chronological gallery of recent confirmed screenshots filling the rest. Double-clicking a thumbnail opens a full-image overlay. Gallery items are collected off the UI thread from confirmed updates (deduped by event id) and each ImageOp is built once and cached. Cross-compiles for Windows; no new deps. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
