/* ============================================================
   RIWAJ — BECOME A COOK MOTION POLISH  v1.0.0
   Figma-style micro-interactions LAYERED on top of the existing
   design. NO layout/visual changes — pure motion enhancement.
   Pairs with riwaj-bc-pro.css; loaded after it.

   What this adds:
     - Page entry fade-up
     - data-reveal scroll choreography (with stagger)
     - Top scroll-progress bar (3px brand-gradient)
     - Section-title underline draw on reveal
     - Benefit icon springy scale + rotate on hover
     - 3D tilt scaffolding on benefit + commission cards
     - Step-number springy pop-in (scale + rotate from 0)
     - Step arrow gentle nudge
     - Commission "highlight" card pulse glow
     - FAQ chevron rotation (+ → ×)
     - CTA button shimmer sweep + magnetic effect
     - prefers-reduced-motion safety
