   Release page for the 8-Bit Arcade Mega Cabinet.

   House style inherited from smisco.biz/assets/styles.css (dark ground, Syne /
   Familjen Grotesk / IBM Plex Mono). Neon is used as ACCENT ONLY — the
   screenshots carry the arcade energy, the page stays typographic. Cyan is the
   anchor, matching the project's registry colour.
