/*!
 * future-css -- dialog and sheet
 *
 * Built on the native `<dialog>` element, opened with `showModal()`. That one
 * call provides what hand-rolled modals spend hundreds of lines approximating
 * and still get wrong: the top layer (no z-index war), an inert background (no
 * focus trap to write), Escape to close, focus moved in on open and returned on
 * close, and a `::backdrop`.
 *
 *   <button type="button" commandfor="confirm" command="show-modal">Delete</button>
 *   <dialog class="fc-dialog" id="confirm" aria-labelledby="confirm-title" closedby="any">
 *     <header class="fc-dialog__header">
 *       <h2 class="fc-dialog__title" id="confirm-title">Delete this chat?</h2>
 *     </header>
 *     <div class="fc-dialog__body">…</div>
 *     <footer class="fc-dialog__footer">
 *       <button commandfor="confirm" command="close">Cancel</button>
 *       …
 *     </footer>
 *   </dialog>
 *
 * `commandfor`/`command` open and close it without a line of script where they
 * are supported; elsewhere, `dialog.showModal()` and `dialog.close()` are the
 * whole API. `closedby="any"` adds light dismiss on a backdrop click.
 *
 * Motion uses `@starting-style` and discrete transitions of `display` and
 * `overlay`, so the dialog animates in AND out with no JavaScript. Browsers
 * that lack either simply show and hide it instantly, which is the correct
 * fallback.
