/* Click-to-play video card + accessible YouTube modal.
   Behavior: /js/video-card.js. Usage and copy-paste snippet: docs/video-cards.md.

   .vc-section            page section that holds one card
   .video-card            [data-video-card][data-youtube-id][data-title][data-duration]
   .video-card-copy       HTML copy outside the poster: eyebrow, title, text, badge, CTA
   .video-card-poster     the <button> click target (16:9 poster + play button)
   .vc-modal              the shared dialog, built once by js/video-card.js

   Selectors are scoped two classes deep where page stylesheets style bare
   h2/p/button, so the card looks the same on every page. */

/* -------------------------------------------------------------- hero video */
/* .video-card--hero: the poster IS the hero's visual column (app pages greet the
   visitor with the video; the image collection sits directly below the hero).
   No copy column: the hero's own h1/text/CTAs are the copy. Usage: docs/video-cards.md.

   Layout is explicit markup + a named grid, on purpose. The hero grid carries
   .product-hero-grid--video and three children in reading order:
     .product-hero-lead (eyebrow, h1, definition) → .video-card--hero → .product-hero-more
   Desktop places lead/more in the left column and the video in the right; phones
   simply stack them in source order, so the poster sits under the headline.
   Do not reintroduce :has() or display: contents here. PR #97 reflowed the hero
   with `:has()` + `display: contents` + `order`, which removed the IntersectionObserver-
   watched .reveal copy wrapper from the box tree; that was the only structural
   change in the release that froze /mailbaser/ in production. Plain classes need no
   relational style invalidation and keep every observed element a real box. */
