/* Interactive Athena platform architecture diagram.
   Structure (per docs/design/Athena_Naming_and_Architecture.md §2): Athena is the
   container; Functions (7) + Foundations (6) are the two sections inside it; humans
   on the loop above; service lines + existing stack below. Hover/focus a node →
   glass tooltip + the dependency subgraph lights up (connectors flow); click → its
   page. Motion is CSS-driven (GPU-friendly), reduced-motion honored, keyboard-parity. */
