"""Service catalogue.

Each fusion.repair.service.catalog record is a named repair / maintenance
service (e.g. "Stairlift motor replacement", "Bed remote troubleshoot")
with estimated duration, estimated cost, default parts, and symptom
keywords used to auto-match an intake to the right catalogue entry.

The catalogue feeds:
- intake auto-match  -> sets x_fc_service_catalog_id +
  x_fc_estimated_duration + x_fc_estimated_cost on the repair
- visit report       -> default labour line + parts pre-fill
- pricing variance   -> compares estimate vs actual
