/* ============================================================
   Shared marketing-site theme for PerformanceOpti.
   Vanilla CSS, no build step, mobile-first.
   Visual language: Audible / Audiobooks.com — colorful book covers
   doing the work of color, a warm amber brand accent, and generous
   rounded cards that read like a media library. Light is the default
   theme; dark is a user-toggleable option (see themeToggleScript() in
   build.mjs) rather than the only mode — both share the same tokens
   below, just with different values under [data-theme="dark"].
