/* ============================================================
   AdSaathi public site — the shared design system.

   Loaded by /, /product, /privacy, /terms. Everything here is
   cross-page: the typefaces, the colour tokens, the nav, the
   footer, and the document treatment the three text pages share.
   Page-specific styling stays inline in each template.

   The point of this file is that the brand cannot drift. Four
   copies of the same :root block is how a palette quietly ends up
   with four slightly different greens.

/* ── typefaces ────────────────────────────────────────────────
   Subset to Latin (64KB for all five). They carry no Indic
   glyphs on purpose: Hindi/Gujarati/Tamil/Bengali text on the
   landing page falls through to the Noto family the device
   already has, which renders those scripts properly. */
