/**
 * MouseState — the live pointer-position signal.
 *
 * Emitted (throttled) from a global `mousemove` listener wired up in the
 * browser bootstrap. It is a *state* signal, not an event: the bus keeps only
 * the latest value, so any component that mounts later still sees the current
 * pointer position.
 *
 * This example uses it to drive the corner HUD's live coordinates and to prove
 * that several unrelated signal TYPES can travel the same bus and be consumed
 * by `@Are.Signal(MouseState)` typed handlers without interfering with routing.
