/**
 * style.css — WP Smart Lead Popup v1.1.0
 *
 * Design decisions:
 *  - Popup is ALWAYS centred (flexbox overlay, no bottom-sheet on mobile)
 *  - Input icons: SVG absolutely positioned, input has fixed left-padding
 *  - No spinner anywhere — button shows text + arrow only
 *  - Fluid card width: 92vw capped at 420px — works on every screen size
 *  - font-size: 16px on inputs prevents iOS Safari zoom
 *  - Four breakpoints: 480px, 400px, 360px, prefers-reduced-motion
 *
 * @package WP_Smart_Lead_Popup
