Remove shorts recommendation preference, keep a six-video viewed cache window, preload the next two videos after healthy buffering, and avoid premature seen-list resets between sessions.
- Active video loads with priority; next video preloads only after the
active one has 12s of forward buffer or is buffered to the end
- Add high/low watermark hysteresis (12s grant / 4s revoke) so the
preload grant no longer thrashes around the threshold, discarding
already-preloaded data
- Treat buffered-to-end as healthy to avoid revoking preload near the
end of short clips
- Mark sources as cacheable on first canplay and keep src bound for
cached adjacent slides in both directions, so swiping back (and
forward again) reuses the browser buffer instead of reloading
