/* ---- Download gate modal ----
   Deliberately NOT relying on the [hidden] attribute to control visibility:
   author CSS with `display` set always overrides the browser's built-in
   [hidden]{display:none} rule regardless of selector specificity (origin
   precedence in the CSS cascade), so combining hidden+display:flex silently
   fails to hide the element. Using an explicit .is-open toggle class avoids
   that pitfall entirely. */
