   QA10 — mobile.css
   State-of-the-art mobile enhancement layer.
   Loaded AFTER styles.css so plain-specificity rules win by source order.
   Section order (top → bottom = cascade increasing):
     1. TOKENS
     2. RESET / GLOBAL
     3. TOUCH TARGETS
     4. HERO LOGO (fluid clamp)
     5. SAFE AREA (landscape L/R)
     6. STICKY CTA (keyboard-open + safe-area enhancements)
     7. SKELETON LOADERS
     8. BREAKPOINT BLOCKS (iPhone SE)
     9. USER PREFERENCES (contrast, reduced-data, reduced-motion)
    10. FOLDABLES (horizontal-viewport-segments)
    11. CONTAINER QUERIES
    12. VIEW TRANSITIONS
