   SvarKlar - site-wide stylesheet.

   Tokens live in tokens.css (loaded BEFORE this file). This file
   covers chrome shared across every page: layout primitives, CTA
   pills, header + nav, base hero, hub dashboard primitives (used by
   home + /services/), FAQ, final CTA, footer, plus the mobile nav.

   Homepage-only sections (hero card, mock inbox, value blocks,
   pricing, founder, palette arc) live in home.css. Per-page
   stylesheets layer on top (about.css, services.css, etc).

   Section order:
     1. Layout primitives + accent <em>
     2. CTA pills
     3. Header
     4. Hero (base; .t-hero-card lives in home.css)
     5. Hub dashboard primitives (.t-hub-*)
     6. FAQ
     7. Final CTA
     8. Footer
     9. Founder reassurance (canonical)
    10. Responsive
    11. Mobile nav
