/* =========================================
   AIR / ENFORME — entry.css (FINAL)
   - Fixed centered chrome + sparkles title (AIRCHIVE vibe, darker)
   - Back button stays above everything
   - Swipe/scroll-snap works on BOTH desktop + mobile (same behavior)
   - Clean stacking: grain < main < CRT < title/back < lightbox
