/**
 * GET /api/the-nook/releases.json
 *
 * The release list behind The Nook's Settings > Changelog tab, newest first:
 * `{ releases: [{ version, build, date, sections: [{ title, bullets }] }] }`.
 *
 * Same source as /changelog — the Sparkle appcast plus the checked-in archive
 * of releases older than its retention — so the app and the website tell one
 * story. Section titles and ISO dates instead of HTML keep the client from
 * parsing markup it would only take apart again.
 *
 * Five-minute cache, in step with the appcast route. An unreadable appcast is
 * a 503 rather than an archived-only 200: the app keeps the newest release in
 * its own bundle and falls back to it, which beats showing stale notes as if
 * they were current.
