/*
 * Landing-page form styles (LANDING-006).
 *
 * Two render modes:
 *   1) Modal dialog (book-a-demo from CTA buttons) — uses native <dialog>
 *   2) Inline form (contact.html) — same form, no dialog wrapper
 *
 * Reuses Milan's existing CSS tokens (.btn, .btn-primary, body color/font).
 * No new design language introduced.
