/* ==========================================================================
   Bass Daddy Devices — site.css
   Layout and page-level composition. Loads AFTER bass-daddy.css.

   Rules for this file:
   - It may only compose. It never redefines a token or a .bdd-* component.
   - Every value comes from a var(--…). No raw hex, no magic pixel sizes
     outside the 4px space scale.
   - bass-daddy.css ships no layout primitives (.row and .grid don't exist),
     so the shared ones live here.
