/* Zero-JS modal: a checkbox drives visibility via `:checked ~` sibling selectors.
   The checkbox itself stays in the DOM (visually hidden via .visually-hidden in base.css,
   not display:none) so it stays a real, keyboard-focusable, Tab/Space-operable control —
   every trigger and the close control are <label for> elements pointing at it. See
   NOTES.md for the tradeoffs this pattern accepts (no Escape-to-close, no backdrop-click). */
