/* ============================================================================================================
   THE HEAD: READ and WATCH (2026-10-03). The site's menu, its four ways in condensed into two doors.
   Source of truth: Code/head/assets/css/head.css → the theme's assets/css/head.css. Manual: Code/head/README.md.
   Printed by header.php AFTER wp_head(), so it follows style.css and wins at equal specificity. Every rule is scoped
   to the new markup (.ll-head, .ll-sheet, .ll-door, .ll-room, .ll-head-scrim): if head-doors.php ever falls back to
   the plain menu, nothing here touches it.
   The design system holds (design-system.md): dark; #ef4444 the accent, never blood red as type; every number white;
   the neon seam's glow is drop-shadow, never box-shadow; Plus Jakarta Sans, display at 800 / -0.035em; drawn icons.

   A page whose hero runs under the bar puts `ll-over-hero` on <body> and `data-ll-hero` on the hero. While the page
   sits at its top, the bar is see-through over the hero's art, with a soft shade so the words stay legible over bright
   art; the moment the page scrolls (head.js adds `ll-hero-passed`), it is the bar every page has, so nothing of the
   hero passes under a see-through bar. An open door or the phone menu makes it solid at once. Without head.js (no
   `ll-hero-js`) the bar never goes see-through. */
