/* =============================================================
   Adarsh Bellahalli — "Datum" theme
   Authored for this site; Adarsh Developers' first microsite.

   Design intent: a measured, structural, all-sans system. Flush-left
   display type, hairline rules instead of shadows, numbered section
   index, square corners. Nothing decorative carries meaning — the
   numbers do.

   Palette from builders/adarsh-developers.json.
   Contrast note: --brand-primary #1c75bc is 4.86:1 on white, so it is
   safe for body-size text on light. --brand-tertiary #0f4670 (10.0:1)
   carries anything that must stay legible at small sizes or over tint.
