/*
 * DNSVault ID — design system
 *
 * Hand-authored, Propshaft-served (no build step, no Tailwind). Matches the
 * light, clean modern-SaaS TONE of the rpzdb app: soft slate background, white
 * cards with a hairline border + gentle shadow, blue primary, system font.
 *
 * Layout:
 *   1. Design tokens (:root custom properties)
 *   2. Base / reset niceties
 *   3. Layout shells        (.page, .topbar, .auth-shell, .auth-card, .content)
 *   4. Typography helpers
 *   5. Forms                (.field, .btn, .btn-primary, .btn-secondary)
 *   6. Flash banners        (.flash)
 *   7. App grid / tiles     (.app-grid, .app-tile)
 *   8. Status pills         (.pill)
 *   9. Misc (org-switcher, QR, code, empty-state)
 *  10. Reduced motion + dark mode
