Behavioral Drift
Models day-to-day unpredictability via N(1.0, σ=drift/2) clipped to [1−drift, 1+drift].
{{ driftPct }}
0 — none 1 — max
Draw from N(1.0, {{ driftSd }}) clipped to [{{ driftLo }}, {{ driftHi }}]
Drift = 0 — all days use exact baseline (deterministic)
locked random

♻️ Greywater Recycling
Accumulated grey water from the previous day (shower, sinks) is redirected to toilet flushing, reducing fresh water consumption.
Open Plan → Tank capacity & daily change to see fresh and grey runway.
