Pagination (regression): the IntersectionObserver sentinel only fires on intersection *changes*, so a short first page kept it on-screen and it never re-fired — stuck at 20 — and I'd hidden the Load more button whenever IO exists, leaving no fallback. Now: - Load more button is always shown while there's more (the reliable control). - Auto-load is self-correcting: track sentinel visibility and, after each load, pull again via rAF if it's still on-screen (rAF lets the observer update first so a cached category doesn't load every page at once). - page increment moved inside loadGrid so the button + sentinel can't double-bump. Caching: cachedFetch() memoizes /discover/list responses per URL for the session (rails + grid pages) — revisits, paging and reopening a category are instant and don't re-hit TMDB. Responsive: small-screen pass for the Browse panel, hero (height/title/actions full-width), grid header wrap, and the trailer close button (kept on-screen). Also fixed the ambient layer's 130% width that could cause horizontal scroll.
