/**
 * Email Template Builder — Shared UI Stylesheet (Review round 2)
 * CertifID EMD Tools
 *
 * Round-2 refinements (all five options share these):
 *   - Template chooser is a custom DROPDOWN (matches the PDF builder) so more
 *     templates can be added later.
 *   - No "new asset type" badge.
 *   - Formatted + Plain text are BOTH available (toggle / both shown), framed by
 *     each layout option.
 *   - Copy actions live OUTSIDE the document sheet (toolbars / rails / headers).
 *   - "Sign-off" is an editable detail (set once), not a per-recipient placeholder.
 *   - "Recipient name" is an optional field that falls back to the [placeholder].
 *
 * Layout-specific arrangement lives in each option's own <style> block.
 *
 * Dependencies: Inter (Google Fonts), Thicccboi (@font-face in HTML), Tabler Icons.
