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.

+## R-240. 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%. Nobody would run that at a
+table, and the rule was wrong rather than merely coarse.
+
+A lamp now has a **reach**, and it is per item rather than global, because a weapon
+lamp and a vehicle searchlight are not the same offer — 6 m, 10 m for the issue field
+lamp, 4 m for cold light strips, 30 m for a roof searchlight. Anyone inside the reach
+is in the light, and the card names whose lamp it is: *"MODE: Tomas's, 4 m away — you
+are in it."* Both halves of the rule travel together, so the pool is one position and
+the whole group is standing in it.
+
+Measured from the tokens, because the canvas already knows who is standing where. The
+same shot that started this — Rakhi, no lamp of her own, four metres from Tomas's, in
+pitch dark — went from **20% to 60%**, and Ceyla twenty-five metres out still ate the
+full −50%.
+
+**The interesting part was the unknown.** `Number(null)` is 0, so an unmeasured
+distance read as *standing on top of the lamp* and would have lit any scene with no
+tokens placed. My own spot-check caught it before it ever ran: an unknown distance is
+now explicitly not lit, and the dialog carries a tick that arrives pre-set when the
+canvas could measure it and is the GM's answer when there is nothing to measure. That
+keeps it automatic where it can be and honest where it cannot, rather than quietly
+lighting the world.
+
+Note for deployment: `template.json` is read when Foundry loads the system, so the new
+`lightReachM` field did not exist on items until the server was restarted — the
+migration then stamped it. A remote server needs the restart, not just a pull.
