  "_note": "Source-of-truth for Remotion scroll-capture previews of the v1.1 showcase pages (the 4 new themes + the 5 bespoke/custom pages). A Remotion composition iterates `demos`, loads each `url` in an <Iframe> at `viewport`, animates scrollTop from 0 to (content height - viewport.h) across `durationSec` (ease in/out, hold ~0.6s at each end), and renders to `out`. Drop the resulting .mp4 into site/_tests/_thumbs/ and swap that card's <img> for <video data-hover-play src=... poster=...> in index.html. Hallmark does the page; Remotion does the scrolling. (The original 8 example cards already ship pre-rendered loops and are not listed here.)",
