/*
  agniai.store v2 — global stylesheet
  Dark theme. Slightly different accent (purple-blue #6366f1) than shopagni.com (#4f8fff)
  to signal it's a sibling brand under Agni Consulting, not the same thing.

  Built specifically for SMB owner-operators (vet / chiro / HVAC) — bigger fonts,
  warmer palette, less "B2B SaaS" feel than shopagni.com.
