/* ============================================================
   Shared small-screen primitives — drop-in.
   Generic phone-width rules every draft wants, kept in one place
   so taps stay ≥44px and body padding stays comfortable across
   all designs. Section-specific stacking (hero, router, pricing,
   proof) stays per-draft — those grids differ by design.
   Include AFTER the draft's own base styles.
