* HLS Video Player - Initializes HLS.js for IPFS-hosted videos

  * All four load on every page from the extension's BeforePageDisplay hook,
  *   <div class="hls-video-player" data-cid="QmXet6..."></div>
* exactly as they did from here, and each does nothing unless the form or
* element it cares about is on the page being shown. Changing any of them is
* a pull request now: reviewed, syntax-checked by CI, deployed by Jenkins —
* rather than several hundred lines pasted into this box, which is how the
  * whole of this file went down for 23 minutes on 15 September 2026.
  *
  *
  * The gadget loads hls.js and initializes players for any element
  * What remains below is the user-subpage zine styling. It stays because it is
  * with the hls-video-player class and a data-cid attribute.
* bound to classes defined in MediaWiki:Common.css, and moving the script
  * without its stylesheet would split one feature across two homes. It goes
* next, with the CSS, after which this page can be empty.
  *
  *
  * Supports both HLS streams (CID/master.m3u8) and raw video files.
  * See cryptograss/pickipedia#124 and #131.
* Tries HLS first; if the manifest 404s, falls back to direct playback.

/**
 * What used to be here now ships with the PickiPediaReleases extension.
 *
 *   the HLS video player   -> ext.pickipediaReleases.videoPlayer.js    (#124)
 *   Blue Railroad date picker -> ext.pickipediaReleases.blueRailroadDate.js (#131)
 *   "X blocks ago"         -> ext.pickipediaReleases.blocksAgo.js      (#131)
 *   Instrument form checks -> ext.pickipediaReleases.instrumentForm.js (#131)
 *
 * All four load on every page from the extension's BeforePageDisplay hook,
 * exactly as they did from here, and each does nothing unless the form or
 * element it cares about is on the page being shown. Changing any of them is
 * a pull request now: reviewed, syntax-checked by CI, deployed by Jenkins —
 * rather than several hundred lines pasted into this box, which is how the
 * whole of this file went down for 23 minutes on 15 September 2026.
 *
 * What remains below is the user-subpage zine styling. It stays because it is
 * bound to classes defined in MediaWiki:Common.css, and moving the script
 * without its stylesheet would split one feature across two homes. It goes
 * next, with the CSS, after which this page can be empty.
 *
 * See cryptograss/pickipedia#124 and #131.

/* ============================================================
 * Pickipedia — User-subpage zine/Substack styling
 *
 * Layout:
 *   - corner logo (absolute-positioned upper-left of viewport,
 *     OUTSIDE all wiki wrappers — does not push content down)
 *   - non-sticky topbar (just nav) at top of body
 *   - hero block with title (top), then USER:Username kicker below,
 *     optional dek + meta
 *   - light/dark mode toggle (persisted in localStorage)
 *
 * Variant from HTML comment marker `pickipedia:variant=letter|masthead`
 * or category membership; default letter.
