/*
 * GDK Digital - Shared CSS for auth pages.
 *
 * Used by: login.html, register.html, forgot-password.html, reset-password.html,
 * verify-email.html, resend-verification.html.
 *
 * Created 2026-05-13 (BATCH 14 of autonomous fix sprint, T-048). Pages should
 * load this BEFORE their page-specific style block, so that page-specific
 * overrides win. Per-page inline CSS can then be reduced to only the bits that
 * actually differ.
 *
 * Tokens align with website/css/style.css design system.
