/*
 * Hack Pompey Online, November 2026.
 *
 * Loaded after /styles/global.css, the shared template, and overrides it the
 * way each event's own stylesheet does. This one takes the look of the event
 * platform it sends people to: blue-black ink, a faint grid like the
 * platform's plane, outlined blocks with amber corner marks, and IBM Plex.
 * The fonts are served from here rather than from Google, for the same
 * reason the platform does: a font request tells Google who is reading.
