   kBenestad — unified forms design language
   Shared foundation for invoice · timesheet · reimburse
   ----------------------------------------------------------------------------
   Customer-facing white-label apps: the CUSTOMER's identity leads (logo + org
   name in the header); kBenestad is the quiet craft signature.

   Configurable in each app's config.yml (sensible defaults shown):
     accent-colour: "#2F6FED"     → --accent     (recolour to the customer brand)
     font-size:     1.0           → --font-scale  (screen text multiplier)
     code colours (timesheet)     → per-chip --chip-border / --chip-bg
   ----------------------------------------------------------------------------
   Type: Schibsted Grotesk (text) + JetBrains Mono (figures), system fallback
   so the forms render fully offline if the webfonts are unavailable.
