Slice 2 of the lighting generator (ADR-0023): detect non-LED bulbs
(incandescent + CFL + low-energy-unknown > 0) and emit one "Lighting"
Recommendation whose single low_energy_lighting Option converts every bulb to
LED — the overlay sets led = total, the other three counts 0. Priced as a flat
per-bulb average x the non-LED count, contingency 0.26; the description names
"LED" while the measure_type stays MEASURE_MAP-aligned. None when already
all-LED or no bulb counts are lodged.
