/* ============================================================
   Solverra Mega Menu v3 -- full stylesheet (panels, cards,
   quick-links rail, palette, mobile drawer, sticky shell).
   The CLOSED-state structure + sticky/condense shell +
   reduced-motion guard are inlined as critical CSS by the PHP
   (solverra_mm_critical_css). This file is the heavier layer
   enqueued normally.

   Consumes ONLY design-system tokens (--color-*, --sol-* etc.,
   --r-*, --shadow-*, --ease-*, --dur-*, --container, --bp-*).
   Dark mode comes for free: the design system re-emits --color-*
   responsive to html[data-theme] / html[data-theme-effective].

   WCAG 2.2 AA: 44px targets, focus-visible rings, no color-only
   state. GPU-cheap reveal: transform + opacity only.

   ASCII-only per STANDARDS Section 19.1.
