   HOLLOW SLIP WP — Shared stylesheet
   --------------------------------------------------------------------------
   One stylesheet for every page of the fan network.
   Palette (owner's brand): black, red, white — carried over from the
   original site's nightclub theme. System fonts only: the site must never
   depend on an outside service to look right.
   Sections:
     1. Base            5. Hero stage + disco ball   9.  Cards & catalog
     2. Ambience beams  6. Lights-off (blackout)     10. Story demo
     3. Header & nav    7. Hero text                 11. Footer
     4. Controls        8. Room doors                12. Reduced motion
