/* TROT Platform — visual system
   Palette is drawn from the operation itself, not a generic SaaS template:
   loam (soil), parchment (the ledger page), moss (growth), water (flow),
   ochre (harvest) used once, sparingly, as the only bright note.
   Type uses only system font stacks — deliberately no external font CDN,
   consistent with the platform's "owned, no outside dependency" ethos.
