/**
 * WPNest GDPR — frontend banner styles.
 *
 * Premium SaaS aesthetic — soft shadows, generous spacing, scale + fade
 * animations. Plain CSS, no preprocessor. The font is a fixed system stack so
 * themes with latin-subset webfonts can't drop Polish glyphs; the colors are
 * CSS variables that class-banner.php derives from the active theme's palette
 * (with configured fallbacks), so the banner adapts to light/dark themes. The
 * values below are the fallbacks used when a browser lacks color-mix.
 *
 * Modes:
 *   .wpnest-gdpr-banner--bottom    sticky bottom bar
 *   .wpnest-gdpr-banner--floating  floating bottom-right popup
 *   .wpnest-gdpr-modal             granular preferences modal
