/* Rollbook landing page. Direction B "Passbook", from the app
   (apps/rollbook/app/src/main/kotlin/dev/machado001/rollbook/ui/theme/RollbookTokens.kt):
   ink on ruled paper, a green cloth cover that carries only the balance, one red-brown ink for
   days spent. IBM Plex Sans speaks; IBM Plex Mono counts — every count and every date is mono.
   No animation, no blur, no gradients, no shadows. */
