/* NOTE: colors.css and player.css are intentionally NOT @import-ed here.
   An @import URL cannot carry the ?v= cache-busting parameter that
   version.js appends to <link>/<script> tags, so the imported copy is
   permanently cacheable - and because an @import resolves after the
   page's own <link>, that stale copy would override the fresh one and
   silently mask every colour change. Each page links these directly
   instead: colors.css on all pages, player.css only where a player
   actually exists (index.html, music.html). */
