Evidence stays labeled
Every shown relationship traces to a named source on the plant guide.
A deliberately narrow scope
The picker contains only plants connected by a stored source-backed relationship.
Finish with the plant guide
Check timing, spacing, light, and water before placing the pair in a real bed.
