/**
 * WooPlus Auth — v2.21.0 lazy-AJAX redesign add-on.
 *
 * This file adds CSS for the new lazy-loaded tab system on top of the
 * existing auth-frontend.css. It is enqueued AFTER the base file so its
 * rules win cascade tie-breaks.
 *
 * Sections:
 *   1. Panel host (transition between fetched panels)
 *   2. Skeleton loader
 *   3. Refined tab strip (taller, animated icon, scale active)
 *   4. Refined buttons (shimmer hover + loading spinner)
 *   5. Refined inputs (1.5px border, focus glow)
 *   6. Password show/hide toggle
 *   7. Magic-link + passkey panels
 *   8. Dark-mode bridge
 *   9. wp-login.php specific
