/*
  Marketing site · components and layout.
  Every colour, size, radius and motion value comes from ../directions/combined/tokens.css (linked, never copied),
  so a fix in the design system reaches the site. Values defined here are marketing-only roles built from those
  tokens (fluid display sizes, section rhythm, the field palette helpers).

  The rules the site keeps from the system:
    people and actions are ink; the AI (Kavitha) is jamun, and on the jamun field the AI is rose. Nothing else is.
    hatching means "not real" (Practice, samples); the mark's right half is the calling-state lamp.
  What the site adds: bigger type, the jamun field as a Committed brand surface, purposeful motion.
