/* ============================================================
   Kanonik design system v3 - "Instrument".
   Cool precise canvas + crisp white records on real elevation +
   chrome on its own dark plane + lifecycle-colour-as-meaning +
   ONE reserved verdigris seal accent.
   Tokens locked to the product workspace mockups
   (project_theme_decision_2026-06-25). Supersedes the editorial
   cream + sage skin. Single shared stylesheet for every page.
   ============================================================ */

/* ============================================================
   Self-hosted display + mono faces (Fontsource, OFL-1.1).
   Vendored into /fonts/ so the site needs no third-party font
   origin: font-src 'self' in the CSP is sufficient. The body
   sans is the system UA stack (no webfont, no CDN). Instrument
   retires italics; the italic face is kept only for legacy use.
