/**
 * C194 — the private reel library over real HTTP (browserless): the list and
 * the detail render for a communication role, the downloads are served by the
 * C193 authenticated media route, the kill switch takes the reel off the list
 * and withholds every file (C193 decision B), and advisor/leader are denied
 * both the page and the mutation route.
 *
 * Reels and their media are seeded through the deployed REST API (admin
 * session) so the server process runs the real hooks; a Local API call from
 * the runner would throw on `revalidateTag` (same reason as the sibling
 * speech-cut spec).
