Owned detail pages sample the poster for the per-title glow, but preview/person
pages fell back to the theme accent because their TMDB images are cross-origin
(canvas taint). Added /api/video/img — a same-origin proxy restricted to
image.tmdb.org (SSRF-safe) — so:
- preview (tmdb) detail samples its poster via the proxy → real accent;
- the person page samples the portrait → per-person accent on the ring/glow/role.
Tests: route registered + proxy rejects non-tmdb URLs.
