/* ============================================================
   RONIL BASU — COMIC ISSUE
   Paper-white comic book: halftone texture, hard offset sticker
   shadows, Bangers display over Archivo body, candy-stripe
   progress. No build step. No framework.

   Motion contract: everything animated lives inside
   @media (prefers-reduced-motion: no-preference) EXCEPT the
   scroll-linked progress fill (position report, not decoration).
   The static page is complete without JS — reveals only hide
   content under html.js + motion-ok.
