/* Reelquill AI — "For product teams" page (product-videos.html): keeping help, onboarding and training videos up to
   date after each release. Loaded after styles.css and uses its tokens, buttons, nav, FAQ, call to action and footer.
   The motion (the release board, the chores, each step's highlighters, the assistant's run, the vault, the before/after)
   is started by js/usecase.js as each part comes into view; under prefers-reduced-motion every part shows its end
   state and nothing moves. Plain CSS, no build step; the site's CSP allows no inline styles. */
