Give the street lamps real pools: 10 m range and 8 energy at physical falloff

+### Street-lamp pools, measured
+
+A new `lamp_late` shot frames a street lamp so the pool under it can be sampled. The lamp is
+`StreetLamp_*` (named so `set_night_mode` can tune it apart from the sconce and marquee glows).
+Attenuation stays at 1.0 — the venue test requires physical falloff — so the pool is made by range
+and energy:
+
+| Setting | Pool | Gap | Pool/gap |
+| --- | --- | --- | --- |
+| old: 16 m, energy 2.2 | 14.1 | 2.7 | 5.2 |
+| 16 m, energy 4.0 | 21.1 | 6.5 | 3.3 (washed) |
+| 8.5 m, energy 6.5 | 11.5 | 1.3 | 8.9 |
+| **10 m, energy 8.0 (shipped)** | **16.0** | **1.3** | **12.3** |
+
+Mean luminance 0–255. The shipped values brighten the pool past the old setting while darkening the
+gap between poles, which is what "pools, not a wash" means numerically.
