"""ATS detection and public JSON API fetching (Stage 2, tier 1).

Scaffold stub -- not implemented yet.
"""
# TODO (Stage 2, tier 1): implement per CLAUDE.md "Stage 2 — ATS detection".
# Detect Greenhouse / Lever / Ashby / Workday from the company website, then call
# their public JSON APIs (no login needed). On success, return both the careers page URL
# AND the first job posting URL (so Stage 3 can skip its own cascade for ATS companies).
#
# Confirmed ATS JSON field shapes (verify live before trusting — see CLAUDE.md Gotchas):
#   Greenhouse: GET https://boards-api.greenhouse.io/v1/boards/{slug}/jobs
#               → {"jobs": [{"absolute_url": "...", ...}, ...]}
#   Lever:      GET https://api.lever.co/v0/postings/{company}?mode=json
#               → [{"hostedUrl": "...", ...}, ...]
#   Ashby:      POST https://api.ashbyhq.com/posting-api/job-board/{slug}
#               → {"jobs": [{"jobUrl": "...", ...}, ...]}
#   Workday:    varies by tenant — needs per-tenant discovery logic
