/* Take Interest · erin walk-through · the cinematic guided overview
   =================================================================
   A short, warm, calm trailer that RESOLVES INTO the product (today.html).
   Layout + motion only. All color / type / radius / shadow tokens come from
   product.css, which is linked FIRST. This sheet adds:
     1. the four motion tokens (THE SETTLE — one gesture, three speeds)
     2. the full-bleed cinematic walk-through layout
     3. the hand-off-to-product resolve overlay
   No external deps. System fonts only. Works from disk. CSP-safe
   (same-origin file, no inline-blocking needs). Honors prefers-reduced-motion.
