A lamp lights the people standing in it

The goods yard fight made the case: three agents inside the same pool of light shot at
-50% while the fourth, four metres away, shot at -10%.

A lamp now has a reach, per item rather than global, because a weapon lamp and a
vehicle searchlight are not the same offer — 4 m for cold light strips, 6 m for a
weapon lamp, 10 m for the issue field lamp, 30 m for a roof searchlight. Anyone inside
it is in the light and the card names whose lamp it is, so both halves of the rule
travel together: the pool is one position and the whole group is standing in it.

Measured from the tokens. The shot that started this — no lamp of her own, four metres
from somebody else's, in pitch dark — goes from 20% to 60%, while an agent
twenty-five metres out still eats the full -50%.

An UNKNOWN distance is explicitly not lit: Number(null) is 0, so an unmeasured
distance would otherwise have read as standing on top of the lamp and lit any scene
with no tokens placed. The dialog carries a tick instead, pre-set when the canvas could
measure it and the GM's answer when it could not.

Note: template.json is read when Foundry loads the system, so a deployed server needs
a restart and not just a pull before the migration can stamp the new field.
