+"""Slim-schema import parsing: same contract as OpenAIResumeImportParser, minus
+model-emitted evidence quotes.
+
+Evidence snippets are matched locally against the source text in ``_to_draft``
+(``_evidence_for`` falls back to field values), so asking the model to emit
+per-item quotes only inflates output tokens and latency. ``import_parser.py`` is
+over the 200-line edit gate, so the slim path lives here and is wired in by
+``ResumeImportService``.
