Do
Keep marketing on warm paper #F7F6F5 with near-black ink; flip the product surface to true-black.
Use ultramarine sparingly — links, active session, one highlight; it's punctuation, not a fill.
Set everything visible in NB International Pro (500 for headings); code & branches in Geist Mono.
Treat agents as a fleet — parallel sessions across Running / Review / Done.
Don't
Reintroduce a Windsurf teal/green identity — the brand is Cognition/Devin monochrome now.
Flood the UI with ultramarine or add a second bright accent — orange is the only secondary.
Set body copy in a mono — NB International Pro carries sentences.
Show a single agent — the many-agent fleet is the whole surface.
