/* ==========================================================================
   InfinitySniper HFX — Website
   The palette is the console application's own theme system. Four themes
   ship in core/ui.js (guardian / navy / emerald / classic) and all four are
   reproduced here token-for-token, so the site wears the same skin the app
   does. Surfaces get lighter as they come forward: bg -> surface -> card ->
   raised, exactly like the Launcher Edition.
