extends CanvasLayer
## InspectTooltip — hover (or long-press) on a world tile to see what's there.
##
## Samples the mouse position every frame, maps to a tile, looks for an entity
## or zone at that tile, builds a short description, and renders a small panel
## offset from the cursor. Empty tile or off-map → tooltip hides.
##
## Touch fallback: long-press on a tile triggers the same lookup and pins the
## tooltip until the next click anywhere (Phase 17 long-press inspect from the
## design doc). Desktop hovering is the primary path on PC; the long-press
## path is wired via Selection's long-press detector (TODO Phase 19).
