/* DateNWed modal contract (CV-T16): native <dialog class="dnw-dialog"> written by converter pass A6, driven by
 * /static/js/dnw-modal.js.
 *
 *   <dialog id="xModal" class="dnw-dialog" data-dnw-modal aria-labelledby="xModal-title">
 *     <div class="... dnw-dialog-panel">           the page's own panel (its colours, radius, width stay)
 *       <div>header (h1-h4)</div>                  fixed
 *       <div class="modal-body">...</div>          scrolls, themed scrollbar
 *       <div>footer (buttons)</div>                fixed
 *     </div>
 *   </dialog>
 *
 * Rules (CLAUDE.md): max-height 85vh then 85dvh; rem only (no px); the overlay look is ::backdrop; dark first.
 * Specificity: the panel rules use two classes so they win over the page's utilities on the same element
 * (`overflow-y-auto`, `max-h-[90vh]`), which would otherwise scroll the whole panel instead of the body.
