/*
  ChronoTab marketing site: the shared shell (RB-9s).

  Tokens, type, buttons, header and footer from the ChronoTab landing page design
  (design kit landing/ChronoTab-landing-page/styles.css; style authority
  brand/ChronoTab/system/DESIGN.md). Every page links this file; the homepage adds
  /css/home.css for its own sections, and each sub-page keeps its page-only rules in
  an inline <style> (the CSP allows style-src 'unsafe-inline', never inline script).

  The site is light-only. Manrope is self-hosted (fonts/manrope-variable-latin.woff2,
  weights 200-800, licence fonts/OFL-manrope.txt), so the CSP stays default-src 'self'.
