/* =============================================================================
 * WI-227 — Hybrid Email Composer styles
 *
 * Modal shell that opens over the inquiry drawer with a two-pane layout:
 *   LEFT  — form (template picker, subject, section toggles, body)
 *   RIGHT — live preview (sandboxed iframe rendering the rendered HTML)
 *
 * Visual language matches ops-drawer / services-modal — pale surface, blue
 * accents, compact controls, generous spacing around the iframe so the
 * preview doesn't feel claustrophobic. Uses booking-links.css tokens
 * (--color-primary, --color-bg-page etc.) already loaded on every admin page.
