## Elevation & Depth

IBM Plex Sans weight 300 (Light) para display — gravitas corporativa com leveza tipográfica. Único acento: IBM Blue 60 (#0f62fe) para tudo interativo. Border-radius 0px em botões primários — retângulos sem suavização. Inputs com bottom-border (não boxed) — padrão Carbon. Profundidade via layering de cor de fundo (branco → gray 10 → gray 20) sem sombras. Grid 2x de 8px com aderência estrita. Token system --cds-* para todas as cores semânticas. Micro letter-spacing (0.16px em 14px, 0.32px em 12px).

- **Physics:** Ease-out curves, 200-300ms duration. Smooth and predictable.
- **Entry animations:** Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items.
- **Hover states:** Subtle color shift + shadow adjustment over 200ms.
- **Page transitions:** Fade only (200ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.
