/* GAPIVO design system - PI27. THE single stylesheet.
   Every screen imports this and defines NO colours of its own (verified).
   Tone reference: the accepted PI23 page - clear, factual, no hype;
   evidence and assumption visually distinct; honesty states first-class.

   Colour code, used consistently (a reader learns it without a legend):
     --ev    green  = evidence (came from something real, links to it)
     --as    amber  = assumption (we picked it - change it and see)
     --warn  red    = warnings, losses, honest tensions
     --lock  slate  = deliberately locked content (never looks broken)     */
