10//!
11//! Pure functions over `InspectedEntity` / domain tag — no state. Component
12//! authors that want a different icon / tag for their type can extend the
13//! match arms here (or, in a later iteration, register through the
14//! `inventory` registry that already carries per-component metadata).
