/*
 * Gandalf design system — canonical visual contract for every Gandalf surface.
 * Extraction date: 2026-07-20
 *
 * Consumers:
 *   - gandalf-website/ (public site)
 *   - gandalf-wallet/extension/ (popup UI imports this file; composition-only styles.css)
 *
 * Do not fork tokens into product CSS. Product styles compose layout only.
 *
 * Provenance labels used by the companion HTML:
 *   Extracted   — present in production source.
 *   Normalized  — repeated source values promoted to a named token.
 *   Derived     — conservative theme/semantic completion.
 *   A11y fix    — source identity retained with a contrast or target-size correction.
 *   Recommended — reusable state/pattern not implemented in production.
