/*
 * Speaker declarations (/speaker-forms/) — the guest lecturer's signing page.
 *
 * Lifted from `Website Redesign/speaker-forms/mockups/speaker-form.html`, which was
 * calibrated against thl-theme 0.6.16: style.css :root tokens verbatim, contact.css form
 * grammar, sla.css written-page head. The mockup's own chrome (the state switcher and the
 * implementation notes) is not here, and neither are the tokens: :root in style.css owns
 * those and redefining them here would be the drift the Design Guide warns about.
 *
 * 🔴 ENQUEUED ON `is_page_template('page-speaker-forms.php') || is_page('speaker-forms')`.
 * The template renders on the slug alone, but `is_page_template()` reads post meta and
 * returns FALSE when the template was never chosen in the editor, so a slug-only page
 * would load none of this. See `reference_wp_page_template_slug_trap`.
 *
 * 🔴 NO DOWNLOAD BUTTONS ON THE CONFIRMATION. D4 (5 Sep 2026): nothing is stored on the
 * server, so there is nothing to serve. The `.dl` rules the mockup carried are gone
 * deliberately; do not restore them without restoring the storage decision first.
 *
 * 🔴 THIS PAGE RENDERS ITS OWN DOCUMENT SHELL, without the site header or footer (P10).
 * That is why `body` and the reset are redefined below: style.css is still loaded, but the
 * page-level classes it targets are not present.
