"""
Client Growth Profile — the per-customer config that turns Dealix from a
generic operator into a specialized one.

Without this profile every agent works on a generic prompt; with it,
every draft, every Why-Now, and every recommendation is grounded in:
the customer's offer, ICP, sales cycle, channels, objection history,
approval rules, and compliance constraints.
