/**
 * WLIAATrack consent banner styles.
 *
 * Design goals:
 *  - Fixed-bottom bar (not modal) — less intrusive, doesn't trap focus
 *  - Equal visual weight for Accept / Reject / Customize (regulatory req.)
 *  - Works in dark and light contexts via theme CSS custom properties
 *  - Accessible tap targets (min 44x44) and readable text contrast
 *  - Mobile-first; widens to a row layout at 782px (theme's breakpoint)
 *
 * Uses the theme's --wp--preset--color--* tokens where available, with
 * hard-coded fallbacks so the banner works even if this CSS is loaded
 * outside the theme (e.g., a PHP error page rendered without theme.json).
