/* ==========================================================================
   ELLA'S BUBBLES × AITCOH — CO-BRANDED CONSUMER LANDING PAGE
   --------------------------------------------------------------------------
   Look: matches the ella co-brand ad creative. White marble-light foundation,
   bright cyan accents, deep navy serif display headlines (Playfair Display),
   glossy cyan CTA buttons, soft glassy pills. Intentionally lighter and
   simpler than both the dark partner-strategy page and the teal bathrooms
   campaign page (separate campaign, separate look).
   Sections:
     1.  Brand & theme variables (co-brand cyan)
     2.  Reset & base
     3.  Accessibility: skip link + focus states
     4.  Header / co-brand lockup / navigation
     5.  Buttons
     6.  Hero
     7.  Section headers + cards
     8.  Proposition grid + pull quote
     9.  How-it-works flow cards
     10. Live campaign highlight band
     11. Pilot region strip
     12. Closing CTA panel
     13. Footer
     14. Modals (privacy / terms)
     15. Mobile sticky CTA bar
     16. Scroll reveal system
     17. Reduced motion safeguards
     18. Responsive refinements
