   Usecase surfaces — rebuilt on the Get-Ikigai DS primitives.
   Rules followed here:
     - 2px ink borders on every container.
     - Hard offset shadow only (no soft drop).
     - Radius scale: 8 (inputs/buttons) → 16 (cards/bubbles) → 24 (panels).
     - Display face (Anybody) for headlines, numbers, tag-style metadata.
     - Brand blue (p600) is load-bearing: actions + brand moments only.
