/* SPUTNIK #1 - LK design system.
   Loaded after Tailwind Play CDN runtime so tokens + base components
   override Tailwind's defaults where they overlap.

   Hard rules:
   - Short hyphen `-` only, never `-` (em-dash).
   - Self-hosted Manrope (body) + Fraunces (display) - no external font hosts.
   - Public class-name surface used by pages MUST stay stable:
