   Keepflow: AI that keeps work flowing.

   Colour roles follow the brand principle "AI interprets. Workflow
   controls. People decide.": cyan = AI, blue = workflow, violet = people.
   Emerald is reserved for "done" states, amber for "check", red for
   "stop". Fonts are self-hosted (SIL Open Font Licence, see assets/fonts),
   so the site makes no third-party requests.
