/* Tunnel Cobra — support site.
   Palette taken from the game's own Palette enum so the site and the app read as
   one thing. No web fonts, no CDN, no scripts: this has to load on a bad connection
   in an App Store review queue, and a support page that depends on a third party is
   a support page that can 404 through no fault of yours. */
