/* =========================================================
   EDD Class Links pages — shared stylesheet.
   Six per-week pages list every shareable URL the matching
   weekly deck cues the instructor to drop in Teams chat.
   Each row: title, "when to use" context, the on-site URL,
   an Open button, and a Copy-link button that copies the
   absolute https://jeranaias.github.io/... URL.
   Built on top of the site stylesheet (docs/css/style.css).
   Mobile-friendly (single-column collapse below 720px).
