/**
 * VPS Consent — frontend styles
 *
 * Design targets:
 *  - WCAG 2.1 Level AA colour contrast throughout.
 *  - Accessible focus indicators (WCAG SC 1.4.11, 3:1 non-text contrast).
 *  - prefers-reduced-motion: removes transitions and slide animations.
 *  - Mobile-first responsive layout.
 *  - No colour used as the sole differentiator between Accept and Reject.
