/* CycloPilot public site — appearance system, same as access.cyclopilot.app.
   Internal ids: 'asfalto' (dark) and 'terracota' (light). Visitors only see Oscuro / Claro / Automático (Dark / Light / Automatic).
   Values are the approved palettes of Access (styles/globals.css of v4-themes); ASFALTO = the site's existing look, unchanged.
   Both blocks define the same variables; pages only read variables. Without JavaScript the page stays dark. */
