/* ==========================================================================
   Supplier Portal design system: "soft Akte" skin. Tokens + components, NO DaisyUI.
   Layout = Tailwind utilities (compiled bundle); look = these classes.
   Served directly (no build step). See specs/supplier/OVERHAUL.md D5,
   specs/ui/FRONTEND.md ("Skin") and specs/ui/AKTE.md (the parent language).

   Soft Akte = Akte's paper/graphite surfaces, hairlines, semantic inks and
   type roles, with a friendlier finish for an external audience: 6px radius,
   more air, sentence case, and one unmistakable filled primary action.
   Rules: no gradients, no coloured left borders, no heavy shadows (only
   overlays get a faint lift), one subtle page rise, nothing under
   prefers-reduced-motion. Plain CSS only (no nesting, no color-mix), so it
   renders the same in older Android/WeChat webviews.
   ========================================================================== */
