   SALDO — design system for 1CBOOKER (v1)
   One warm paper base, near-black ink, a single loud chartreuse
   reserved EXCLUSIVELY for the primary action. Chamfered geometry
   (clip-path, no border-radius) is the signature motif. Dotted
   ledger grid is the material. Two fonts: Unbounded (display,
   Cyrillic) + Onest (body, Cyrillic).
