- capHlsLevel: also mutate el.api.config buffer fields alongside autoLevelCapping; hlsConfigFor caches at first render (always level 0), so buffer caps never reached higher tiers at runtime without this - priorityIds: pass [] in multiSelectMode — selected players render title- only (no <ReactPlayer>) so they would never call markLoaded and would permanently occupy concurrency slots, starving strip thumbnails - recompute: union priorityIds into effective visible set so the focused channel stays mounted even if its thumbnail scrolls out of the strip - TV.module.scss: update stale comment (players are now unmounted off-screen) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EnhE6P81JhB2ePneazHwMi

Removes stagger/IntersectionObserver loading (PR #143 — Safari unstable). Each thumbnail is now a static <img> refreshed every 4 s via thumbTick and served from thumbnails/{slug}.jpg on Wasabi. Falls back to thumbnails/offline.jpg on error (onError handler). Also reverts the capHlsLevel buffer-cap mutation and bufferCapsForLevel spread in hlsConfigFor that were added as part of the stagger work.
