/* ==================================================================================================
   navrick — site design tokens
   ==================================================================================================
   PORTED FROM THE PRODUCT, DELIBERATELY. Every value below is copied from
   `src/shared/styles/globals.css` so the site and the app cannot drift apart. If you change a colour
   here and not there, the site stops looking like the thing it is selling.

   The governing rule, quoted from globals.css:54–55:
     "Primary actions are NEAR-BLACK, not a brand hue — colour in this app means state
      (recording/ok/warn/err), never decoration."

   So: there is no brand hue. The accent is ink. Saturated colour appears on this site in exactly one
   place — inside faithful recreations of product UI, where it carries state (the orb's four modes,
   the recording red). Nowhere else. No gradients-as-decoration, no accent fills, no green.

   Self-hosted fonts, zero third-party requests. The product's CSP is `default-src 'self'` and the
   site holds the same line.
