Follows #61. Once the server has per-building counts, they should be visible
where the player already looks:

Map mode (M): the RTS overview already draws footprints and follows the
player. Shade each mapped building by its current share of its own 14-day peak
(quiet → busy), and put the count on the building label. The map is where a
campus-wide number belongs.
First person: a building's entrance or floating name is the natural place
for a small bar and a number, e.g. A-huset 340. Labels already go through
WorldLabel / project_to_uv, so this is a new label kind, not a new
projection.
HUD: one line with the Linköping total and the age of the reading, e.g.
Campus 4,850 · 2 min ago, so the number is never mistaken for live when the
fetch has gone stale.

Do not sum the per-building rows: they are rounded individually and do not equal
the city total. Use linköping.csv for the total and the building rows for the
buildings.

Scale: absolute counts mean B-huset always looks busier than Zenit because it is
bigger. The feed can carry a per-building peak from the 14-day window, so the
bar means "busier than this building usually gets", not "more people than the
building next door". The raw number stays next to the bar.

At 03:00 nearly every building reports 10, so the display needs a "quiet" floor
rather than showing six identical busy-looking buildings. A stale feed should
read as unknown, not as empty.

Context update: the map label path this needs now exists (2116f66, #36): buildings are labelled at their footprint centroid and named POIs at their positions, through the same ortho projection. #62 can add the presence bar/count to those labels once #61 lands; no new projection work is needed.
