Thumbnail Loader — Ordered Queue & Viewer-Aware Queue

All thumbnails start with a “not loaded” indicator. Use Start Loading on either approach. Reset clears everything and server counters.

Option 1 — Ordered queue (no burst): start loading and continue as slots open

Strict item order with a client‑side concurrency cap. No initial “first X” burst; just steady flow.

\n \n Client concurrency \n \n

\n\n

Option 2 — Viewer‑aware queue (IntersectionObserver + concurrency cap)

Only loads items near/in the viewport; aborts off‑screen loads; caps in‑flight requests.
