   NotJustAnyMed.Tech Design System
   Shared stylesheet — tokens, documentation chrome, and component styles.

   Built on shadcn/ui conventions. Two token layers, deliberately separate:

     PRODUCT tokens  — shadcn variable names (--background, --primary, --radius…)
                       plus an --alarm-* medical extension. These ship in a SaMD.
     DOC tokens      — --doc-* / --njt-* editorial skin of md.notjustany.tech.
                       These style the documentation and never ship in a product.
