   FreClean | Design System
   Display/Utility: Space Grotesk  |  Body: Inter  |  Data/Mono: IBM Plex Mono
   Palette: deep sky blue + leaf green (from the FreClean mark) on a light
   mineral-white surface, with a warm sun-gold reserved for single actions.
   Signature motif: the "wipe" | a diagonal blue-to-green streak used as a
   section divider, echoing a cloth pass across a surface and doubling as
   the step-marker for the Web3 payment states.
