+  # Attribute Mapping DSL
+  #
+  # This DSL defines how attributes from a QuickBooks Online (QBO) entity
+  # are mapped onto a local ActiveRecord model during synchronization.
+  #
+  # Each mapping registers a lambda in `attribute_map`. When a remote QBO
+  # object is processed, the lambda is executed to extract and transform
+  # the value that will be assigned to the local model attribute.
+  #
+  # The DSL supports several mapping patterns:
+  #
+  # 1. Direct attribute mapping (same name)
+  #
+  #      map_attribute :doc_number
+  #
+  #    Equivalent to:
+  #
+  #      local.doc_number = remote.doc_number
+  #
+  # 2. Renamed attribute mapping
+  #
+  #      map_attribute :total_amount, :total
+  #
+  #    Equivalent to:
+  #
+  #      local.total_amount = remote.total
+  #
+  # 3. Custom transformation logic
+  #
+  #      map_attribute :qbo_updated_at do |remote|
+  #        remote.meta_data&.last_updated_time
+  #      end
+  #
+  #    Useful for nested fields or computed values.
+  #
+  # 4. Bulk attribute mapping
+  #
+  #      map_attributes :doc_number, :txn_date, :due_date
+  #
+  #    Convenience helper that maps multiple attributes with identical names.
+  #
+  # 5. Foreign key / reference mapping
+  #
+  #      map_belongs_to :customer
+  #
+  #    Resolves a QBO reference object (e.g. `customer_ref.value`) and finds
+  #    the associated local ActiveRecord model.
+  #
+  # 6. Specialized helpers
+  #
+  #      map_phone :phone_number, :primary_phone
+  #
+  #    Extracts and normalizes phone numbers by stripping non-digit characters.
+  #
+  # Internally, the mappings are stored in `attribute_map` and executed by the
+  # SyncService during `process_attributes`, which iterates through each mapping
+  # and assigns the computed value to the local record.
+  #
+  # This design keeps synchronization services declarative, readable, and easy
+  # to extend while centralizing transformation logic in a single DSL.
