/* ============================================================================
   portal.css — the portal shell, written against the estate brand.

   The palette is NOT defined here. brand/nkda-theme.css (linked at build time
   from NKDAgility.Hugo.Appearance/assets/css/nkda-theme.css, the estate's one
   definition of light and dark) loads first and supplies --nkd-* primitives
   and the semantic aliases (--color-*, --text-*, --surface-*, --border-*).
   This file only maps portal roles onto those properties. Do not add hex
   colours here; if the brand lacks a value, it belongs in nkda-theme.css.

   Brand rules: signature purple against generous white space; blue and
   orange as functional accents only; no gradients; purple headings; fluid
   clamp() sizing.
