/* Ragnarok landing — near-black ground, bone type, one glacial accent.
   Implements "Ragnarok Landing v2" (claude.ai/design) as static CSS: every
   inline style became a rule here because the relay's CSP has no
   'unsafe-inline' (style-src 'self'). Fonts are self-hosted for the same
   reason (font-src 'self') — a privacy messenger's landing page should not
   phone Google on every visit. */
