🕯️ Candlelit Stone Nave: Reverb, Light and Shadow Quest

A calm first-person night quest in a fictional stone nave: light eight candles, find five relics and open a secret door while measuring how long a clap rings (T60 from 10 s empty to 5.6 s with 40 people), how candlelight fades as 1/d², and how stained glass colours the moonlight.
