{#
The booking modal. Extending htmx_modal.html.twig keeps it a standalone fragment -- it is a
valid response on its own, which is what the opener's hx-swap="beforeend" onto <body> needs.
The form targets the modal itself with outerHTML, which does double duty:
* invalid submit -> Symfony returns 422, htmx swaps it (see responseHandling in app.js) and
the modal replaces itself with the errors showing;
* success -> the response is nothing but out-of-band board blocks, so the modal is replaced
with an empty fragment, i.e. it closes.

{# Root-level errors, which is where a rejected booking lands -- form_end/form_rest does
NOT render these, so leaving this out makes the 422 path silently blank. #}
