Usage rules
- One hue. Tangle is indigo: every gradient is an indigo luminance ramp, never a hue ramp. Multi-hue gradients are banned.
- Indigo is the material, not the accent. The dark canvas glows indigo; chromatic emphasis is rationed to one moment per screen.
- Every number is data: costs, latencies, span IDs, dates, and versions are set in mono with tabular figures. Mono is never decoration.
- Display type stays at weight 600 or below with tight tracking.
- Semantic color carries real state, eval pass or fail, gate results, diff add or remove, never mood.
- Generated artwork lives in three slots only: full-bleed atmospheres, product-card art, and social covers. Decoration is code-native and derived from product geometry.
