/* QRnaka - design system (no build step). Tokens, base, layout, components, pages.
   Look: the QR Hug brand kit (design/qrnaka-qr-hug-brand-kit-v1) - cream paper, deep forest ink, one forest accent,
   light mint on dark, the kit's yellow only in the logo (no purple-blue gradients, no sparkles, no cards in cards).
   Rules (kv-flow 02 §3): one type scale, 4/8 px spacing, thin icons, real dark mode, 150-250 ms motion,
   inputs 16 px, tap targets >= 44 px, nothing wider than the screen at 320 px. */
