/* ==========================================================================
   Kendok — stylesheet
   Minimalist, single-page site. One accent family (indigo, from the logo),
   restrained neutrals, system fonts (zero third-party requests → fast + GDPR-
   clean, no calls leaving the EU). Personality comes from the typographic
   treatment and the "index/measure" motif, not from decoration.

   Edit guide:
   - Brand colour lives in ONE place: --brand (see :root). Set it to the exact
     hex of the Kendok logo and the whole palette follows.
   - To use a self-hosted brand font instead of system fonts, drop a .woff2 into
     assets/fonts/ and see the @font-face stub at the bottom of this file.
