/* ==========================================================================
   Michael Herbst - CV site stylesheet
   Aligned to the live Kouga Digital design system (kougadigital.co.za),
   2026-07 revision: tokens, IBM Plex Mono + Sans, web type scale, header
   wordmark + nav, ink hero, kicker, numbered sections, card / callout /
   badge / item-row components, CTA band, ink footer, a11y patterns.

   2026-08 revision: the raw brand palette is now mapped through a semantic
   token layer (--bg / --surface / --text / --rule / --link ...) so the whole
   site can honour prefers-color-scheme without duplicating component rules.
   CV-specific extensions are marked in their own blocks.
