The M overview is pure geometry and a crosshair. hud::paint_labels
returns immediately when hud.in_map is set (hud.rs:598), so there is no text
anywhere in the map view -- no building names, no POI signs, no room labels.

All of the machinery to do this already exists and already runs every frame in
first person:

liuverse_world::locate (lib.rs:105) resolves building + floor + room from a
point
hud::poi_labels (hud.rs:668) walks every marker and returns borrowed &str
with a range filter
WorldLabel + project_to_uv (frame.rs:448) project a world position to
screen

The ortho map camera has a height and a scale, so labels need a scale-dependent
range and de-duplication by building rather than by proximity -- at campus scale
you want "A-huset" once, not once per floor.

Cheapest visible improvement in the codebase, and it touches no bake data at
all.
