/**
 * VoiceFlow — Modal potwierdzenia zakupu (styling).
 *
 * PHP port target: tools/voiceflow/checkout-modal.php
 * Source parity: VidFlow's static/buy_credits_v2.css:505-673 (2026-06-30 snapshot)
 * with `.bcv2-modal-*` → `.vf-modal-*` prefix rewrite for BoostItUp naming.
 *
 * Structural + visual parity preserved:
 *   - fixed overlay with blur backdrop
 *   - scrollable modal box with gradient background
 *   - identical spacing (32px horizontal padding for sections)
 *   - PayU indigo (#a5b4fc) + Przelewy24 red (#f87171) card logos
 *   - "no default provider" state — user must click
 *   - CTA disabled until consents + invoice-valid + provider picked
 *
 * VoiceFlow product-specific additions (marked in code):
 *   - `.vf-modal-buyer-section` — guest checkout fields (VidFlow assumes login+profile)
 *   - fonts: reuse existing Outfit from /fonts/fonts.css (already loaded on VF page)
