   India-Recalibrated CVD Risk Calculator — calculator.css
   Migrated onto the Monochrome Editorial design system (DESIGN.md / --ds-* tokens):
   monochrome ink-on-paper, hairline borders, sharp 2px radii, DS accent for
   interactive state, DS type. The ONLY non-token colors are the semantic clinical
   risk scale (amber/orange/red escalation + slate "low") applied inline from JS —
   these encode data meaning, not chrome. No teal, no green.
