"""Lever postings — public endpoint behind `jobs.lever.co/<token>`:
`GET https://api.lever.co/v0/postings/{token}?mode=json` → [{id, text, categories:{commitment, location, team, department, allLocations},
country, workplaceType, hostedUrl, applyUrl, createdAt(ms), salaryRange?}]. EU tenants use api.eu.lever.co. Verified 2026-09-12 against the
`palantir` board (fixture trimmed to 20 postings, descriptions removed)."""
