"""Browser Use fused fallback: find careers page AND extract one job URL in one session.

Scaffold stub -- not implemented yet.
"""
# TODO (Stage 2/3 last resort): implement per CLAUDE.md "Stage 2 — tier 6" and "Stage 3 — tier 5".
# This is the LAST tier of the cascade. Fires only when all cheaper tiers in cascade.py
# and extract.py have failed. One Browser Use agent session does both:
#   1. Navigate to the company website and locate the careers/jobs page.
#   2. From the careers page, return the URL of one open position.
# Graceful degradation: if Browser Use / Playwright / LLM key are unavailable, log clearly
# and return (careers_url=None, position_url=None) so the pipeline records needs_review.
