   Palette: deep indigo (trust/tradition) + marigold (warmth/energy)
            + maroon (emphasis) on a warm cream ground — inspired by
            Indian school uniform/stationery palettes, not generic
            "education blue".
   Type: Fraunces (serif, characterful) for headings = institutional
         gravity; Inter (humanist sans) for body = readability.
