/* Signals hub: an arcade radar station. A retro site, not a retro theme:
   the hero is copy on the open night with the radar in a btop-style terminal
   window beside it (as on /about/), the feed sits in an open 2px frame (no fill,
   the title on the border), the page name is an echo sign, the feed reads like a
   high-score table with a 1P cursor, filters are arcade toggles, and verdicts
   are pixel chips. Tokens only; every rule is scoped to .sig-hub so post
   pages that load this file are untouched.
   One continuous night: no colour bands; a quiet dotted seam between the
   sections below the feed (.seam, drawn in qs.css). Rhythm, shared
   with the other inner pages: sections pad var(--sec-y); the close h2 never
   outweighs the page h1 (both 44px, stepping down together). */
