/* ===========================================================================
   RESONANCE LOUNGE - EVENT SITES (Spec 14 section 8)
   The default theme of every hosted event site. Same-origin, embedded in the
   assembly, nothing third-party. A tenant overrides the tokens below with a
   <style> block the server writes from validated values (ThemeCss); it never
   ships a stylesheet of its own, which is what keeps one description rendering
   on a festival's site and a company's alike.

   Tokens from Docs/Specs/ResonanceLounge_Colors_02_System.html: Void ground,
   Cosmic cards, one hero, Cyan links, Amber the rare accent, body text only in
   Starlight or Muted Lilac. Poppins, self-hosted.
