   2Sight — Linear design system (linear.app / awesome-design-md)

   Fidelidade ao sistema:
   - Canvas #010102 (quase-preto com tinta azul) + escada de superfícies
     charcoal (surface-1..4) e hairlines no lugar de sombras.
   - Lavanda #5e6ad2 ESCASSA: marca, CTA primário, foco e ênfase de link.
   - Verde #27a644 é a única cor semântica (status/sucesso).
   - Botões raio 8px (nunca pill), display weight 600 com tracking negativo
     agressivo, eyebrow com tracking positivo, mono para tokens técnicos.
   - Cores ricas só DENTRO de mockups de produto (regra oficial do sistema).

   Motion: "a página é a entrega" — o scroll percorre as 48h de construção.
   Estados iniciais ocultos ficam atrás de `html.js` (progressive enhancement).
