# TODO (Stage 2 tier 5 / Stage 3 tier 4): implement per CLAUDE.md "Cheap-LLM classification".
# Uses Pydantic AI (model-agnostic) with the `classifier_model` from config.
# Two typed tasks:
#   1. classify_careers_link(anchors: list[Anchor]) -> CareerLinkResult
#      Given extracted <a> tags from a page, pick the careers/jobs page URL.
#   2. classify_job_link(anchors: list[Anchor]) -> JobLinkResult
#      Given extracted <a> tags from a careers page, pick one open-position URL.
# Both return a typed Pydantic result including the chosen URL and confidence.
# Graceful degradation: if llm_api_key is placeholder or call fails, return None.
