/* =============================================================
   Chhaya Digital — brand landing page
   Design notes (per impeccable slop rules):
   - No gradient text, no radial glows, no glassmorphism
   - Flat surfaces + one deep green accent + one burnt orange
   - Fraunces (display serif) + Schibsted Grotesk (body)
   - Cards use a defined border, not hairline + wide shadow
   - No eyebrow labels above headings; plain editorial rules
