/* ============================================================
   STICKY MOBILE CTA BAR + JOIN-BY-CODE FORM
   ============================================================
   Two small conversion components shared by index / hosts /
   players. Wiring lives in main.js (guarded on element
   presence, like the rest of that file).

   Sticky bar layering is deliberate: z-index 65 sits above page
   content but BELOW the mobile drawer backdrop (70) and drawer
   (80) in nav.css, and below the cookie banner (9999) - so the
   bar needs no JS suppression while those are open; they simply
   cover it.

   All colors read theme tokens so every palette (Local / Green
   Room / Blue Hour) and the light themes work unchanged.
