   Rival Search MCP — landing page stylesheet
   Single-file static site. No build step.

   Brand: phosphor-green world + ember Rival/Search wordmark (dual-tone).
   Two modes share one identity:
     · DARK  "Matrix"  — green on near-black, ember wordmark
     · LIGHT "Paper"   — deep emerald on warm white, burnt-ember wordmark
   Toggle persists in localStorage; first visit follows the OS preference.
   All colour pairs are WCAG-AA checked (see comments).
