/* ===========================================================
   AMS Interventions — visual system
   Shares the palette and typefaces of the AMS Planning Hub.

   House rules (these are what keep it from drifting):
     1. Radius: 0. No rounded corners anywhere.
     2. No enclosures. Nothing gets a full border. Separation
        comes from hairlines, ground shift, and space.
     3. Colour is a mark, not a container. Tier is a short bar.
     4. One rule weight: 1px hairlines. 3px only where something
        genuinely escalates (the safety referral).
     5. Type does the hierarchy. Fraunces names things,
        Outfit says everything else.
