How seeds in soil wait as a bank
A soil seed bank is living seeds, dormant underground, waiting for a cue rather than gone.

From the opening
A seed bank is the population of living seeds already in the soil, some from last season and some from many seasons ago. They wait in dormancy until light, moisture, temperature, or another cue tells a given species that the surface is worth a try. The opening covers dormant seeds stay viable underground, light and disturbance are cues, and depth shelves seeds out of reach.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
