Place a seed and it will be ready in three breaths — no sooner, no later.
Place a lantern and its light ripples outward one ring each breath, then fades.
A seed becomes a bloom only if the light is touching it the moment it's ready; miss the moment and it turns to moss.
Blooms pulse once. Chain them.
One thing the garden won't tell you: blooms and moss are solid — they block the light. A ripple breaks against them, so your own dead cells become walls.
