/* Shared base for every route: homepage, mod library, game pages and licence.
   The site is built like a game's front end: a warm graphite ground lit from
   the upper right, warm off-white type, thin warm rules for frames, vermilion
   for the selected item and the one primary action, and gold for focus and
   unlocked states. Menus carry diamond markers on a rail. Page-specific
   layouts live in home.css (homepage) and mods.css (library, games, licence). */
