Two complementary additions that share the same bridge-not-rewrite
philosophy — reuse the existing single-page channel view instead of
splitting its 2000 lines into five route-driven partials.
/@handle/{tab}: videos / shorts / playlists / posts / about / wall
redirect to the equivalent /channel/{slug}#tab URL (302). The channel
page's existing hash-tab JS already handles landing on the right tab;
these aliases just make the URLs shareable in the YouTube style.
Channel Videos tab Load More: new JSON endpoint
GET /channel/{username}/videos/more returns the next cursor page of
server-rendered video cards. A sentinel + IntersectionObserver below
the grid fetches the next page when scrolled into view, with a Load
More button as fallback. Behavior mirrors the Phase 2 home feed —
users with thousands of uploads no longer get a 300-item grid on
first paint.
