/**
 * Smart Home Compatibility Checker
 * --------------------------------
 * Stylesheet for the [smart_checker] shortcode UI.
 *
 * Design notes:
 * - Every rule is scoped under `.shcc-checker-wrapper` (or its descendants)
 *   so it cannot leak into the host WordPress theme.
 * - CSS custom properties live on the wrapper for easy theming/overrides.
 * - Layout is mobile-first; the form switches to a 2-column grid at >= 600px.
 * - All interactive elements have transitions, hover states, and focus rings.
