/* Glassmorphism CSS Generator — page styles.

   Chrome uses the site's theme tokens (--fg-rgb, --pure, --surface-*, --border)
   like the rest of style.css. The two deliberate exceptions are the preview
   backgrounds and the demo card itself: those are *content*, not chrome — the
   whole point of the tool is to show the effect against literal colours, and
   the card's own look is written from JS at runtime. */
