/* m1.css — PR-1 of M1 UI rewrite (foundation only)
 *
 * Mobile-first stylesheet for honest-router's M1 surfaces. Defines class-name
 * primitives that the React components in `_primitives.jsx` consume; PR-2
 * migrates each surface to render through them.
 *
 * Token sources:
 *   - colors_and_type.css  → --font-sans, --font-mono, --hr-trust,
 *                             --hr-warn, --hr-error-*, --muted, --border,
 *                             --foreground, --background, --muted-foreground.
 *   - this file (top of :root block) → --m1-space-1..8, --m1-bp-md.
 *
 * Class-name contract (asserted by tests/test_m1_responsive_class_contract.py):
 *   .m1-app .m1-banner .m1-nav
