From the opening
Mold grows where a surface stays wet long enough for spores that are already in ordinary air to germinate. Dust, paper, and soap film can be food, and without the water that food sits unused, so the preference is for the wet surface rather than the dirtiest one. The opening covers water as the switch for spores, why a clean shower still molds, and damp materials versus dry dust.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
