/**
 * Startup Waitlist Stack — Presentation Layer: Form & Confirmation Modal Styles
 *
 * Scope: Applies to .startup-waitlist-form-wrap (and legacy .sift-early-access-form-wrap) and nested Bit Form elements.
 *
 * Architecture:
 * 1. This stylesheet styles the frontend demand capture form and the in-page AJAX confirmation modal.
 * 2. Post-DOI token confirmation pages (landing pages clicked from email) are rendered as standalone
 *    HTML cards directly by the PHP plugin (Startup_Waitlist_Enrollment::render_confirmation_html)
 *    and carry their own self-contained inline <style> block.
 * 3. Startups can customize appearance by overriding root CSS variables (--waitlist-*) in their theme.
