# TODO (Stage 2, tiers 2–4): implement per CLAUDE.md "Stage 2 — URL patterns / homepage / sitemap".
# Tier 2 — URL patterns: probe /careers, /career, /jobs, /join-us, /join,
#           careers.{domain}, jobs.{domain} via HTTP HEAD (or GET if HEAD fails).
# Tier 3 — Homepage link scan: fetch homepage HTML, parse with BeautifulSoup + lxml,
#           rank <a> anchors by career/job keywords in href/text, return highest-ranked.
# Tier 4 — Sitemap: fetch sitemap.xml (and sitemap index if present), scan for career/job URLs.
# Each function returns (url: str | None) so cascade.py can return early on first hit.
