/* ==========================================================================
   ACCESSIBILITY FIXES - Horizon Heights Productions
   Purpose: Fix Lighthouse/PSI accessibility contrast audit failures
   Created: February 1, 2026

   These fixes add fallback colors and increase contrast for:
   - Gradient text (color: transparent)
   - Low-opacity backgrounds behind text
   - Elements with backdrop-filter/blur

   Visual appearance is preserved for most users while meeting WCAG 2.1 AA.
