   HisaabCore — marketing site design system
   Brand: deep blue (#1F6FEB, the app icon) → indigo, with an amber spark.
   Type: Bricolage Grotesque (display) + Plus Jakarta Sans (body).
   Aesthetic: warm, confident Indian fintech — generous space, layered depth,
   subtle grain, bold headings with amber underlines. Light canvas, ink dark
   sections for contrast.
