   Thenga — styles.css (non-critical, loaded without blocking render)

   Critical, above-the-fold rules — design tokens, reset, header, logo
   lockup, hero, film media, ticker and the pinned-layout shell — are
   inlined in the <style> block of index.html. This file holds everything
   that is off-screen or hidden at first paint:
   1. Base extras (selection, focus, Lenis)
   2. Buttons + nav states
   3. Chapters (baseline list + pinned overlays)
   4. Liquid swirl
   5. Loader + progress bar
   6. Footer CTA
   7. Responsive
