/* auth-modal.css — shared signin modal used by consumer.html, index.html, admin.html.
 *
 * All selectors are namespaced under .avx-auth-* to avoid collisions
 * with each SPA's own design system. Self-contained styles; no external
 * fonts or icons — emoji + inline SVG only.
 *
 * The modal renders neutral / light by default. To match a dark-mode SPA,
 * each SPA can override .avx-auth-modal CSS variables:
 *   --avx-auth-bg, --avx-auth-text, --avx-auth-border, --avx-auth-primary
