/* paruto.com — design tokens first; everything else reads from these.
   Brand: gold on black, Barlow / Barlow Condensed / Cormorant Garamond (brand.paruto.com).
   System: Apple Human Interface Guidelines, translated for the web —
   · Liquid Glass only on the control layer (nav, menu, paddles, buttons over media); content uses standard surfaces.
   · Gold is the tint: interactive elements and the display emphasis only. Labels and eyebrows stay neutral.
   · Semantic label/fill/separator tokens, an 8-pt spacing grid, concentric corner radii, 44-pt hit targets.
   · Motion is brief, spring-based, paused off-screen, and replaced by fades under Reduce Motion.
   Appearance: dark (default) and light. <html data-theme> is set before first paint by the inline script in
   index.html (saved choice, else the system setting). `.on-dark` keeps media surfaces dark in both themes. */
