/* ========================================
   UNIFIED SCROLLBAR SYSTEM
   Brand gradient thumb (raspberry -> periwinkle), chunky 16px grip.
   Self-contained: the brand colours fall back to literals, so this works
   on pages that load global.css (app, admin) AND on the standalone
   content pages that don't.
   Works: Chrome, Safari, Edge, Firefox · dark + light modes.
   ======================================== */

/* Firefox: no gradient support, so the thumb is the raspberry brand colour.
   Gated to Firefox specifically via -moz-appearance, a Gecko-only vendor
   prefix nothing else recognises. Chrome/Edge now understand scrollbar-color
   too, and once it is set on an element they drop its ::-webkit-scrollbar
   rules entirely, flattening the pill back into a plain square bar - so this
   block must stay invisible to them, not just to whichever engines happen to
   support -webkit-scrollbar (an @supports selector() check for that pseudo-
   element isn't reliably recognised as "supported" even in Chrome itself). */
