"""Direct customer-to-owner contact email: a client's own site visitor asking
a question or requesting a callback (contact_api.py) reaches the business
owner's inbox directly. This is deliberately NOT the agency's leads pipeline
(n8n/lead-intake.json, the leads table, the agency's Telegram) -- that path
still exists separately for prospects contacting the agency itself (the
"DEMO" client_id on the marketing/demo pages), which are genuine sales leads
for the agency, not a client's own customers.

Recipient is resolved via booking_db.list_users(client_id) (the owner's own
login email, e.g. inhaber@<slug>.mivanchenko.de) -- every provisioned client
already has at least one owner account by the time their site can receive
contact requests. Fire-and-forget via mailer.py, same as booking_mail.py/
