/* ============================================================================
   PANEL DESIGN SYSTEM  —  premium Monochrome Black & White, light + dark
   ----------------------------------------------------------------------------
   Retheme strategy: every page in this panel uses hardcoded Tailwind literals
   (bg-[#F9F9F9], border-[#E8E8E8], text-red-600, ...). Instead of editing all
   of them, they are remapped here onto CSS variables. Change a token below and
   the whole panel — light AND dark — follows.

   Geometry: the panel is deliberately SQUARE. All border-radius utilities are
   collapsed onto the --r-* tokens in the "SQUARE GEOMETRY" block.
