/* ============================================================
   QB — 3D DIAMOND SLIDER  v3.2  |  qb-slider.css
   Changes from v3.1:
   - Eyebrow (.qb-eye) now renders decorative badge lines
   - Arrow hover color transitions with JS-driven CSS var
   - Progress bar smooth reset via CSS transition
   - prefers-reduced-motion: all animations disabled cleanly
   - Alignment helpers: qb-align-left / right / center
