Reference design system (extracted from the live site):
- Palette: #047cfb, #84c4fc, #043c7c, #9c7c79, #c3ccd4
- Typefaces: Waldenburg-75357948a2b6a39b, IBM Plex Mono-c20ba633a65a8c57
- Macrostructure: Ecosystem Index
Use the dominant colour for surfaces, the accent sparingly,
and lean on type weight + scale rather than colour for hierarchy.
