## Navy · `--bg-inverse` · `#0F1F3D`

The dark inverse surface - CTA bands, dark heroes, the dashboard nav strip. Heading goes pure white; body lifts to white at 0.72 alpha so the secondary voice stays present without competing.

## Heading on navy

Used for CTA bands + dark heroes.

Headings render pure white (#FFFFFF · ≈16:1 against navy · AAA). Body lifts to `rgba(255,255,255,0.72)` for the lede. `--border-strong` lifts to `#A8B0BD` in this scope so the supporting outline voice stays present.
