  "_comment": "IAB GVL vendor-ID lookup by tracker domain. Conservative seed list — every entry was cross-checked against the live GVL (https://vendor-list.consensu.org/v3/vendor-list.json) at the date in _last_reviewed. Several major ad-tech brands (Meta, Snap, X/Twitter, Reddit, Hotjar) are intentionally absent because they are not registered TCF vendors at this time — the FAZ banner gates them via the standard category mechanism instead. Multi-vendor domains are allowed (e.g. msn.com served both Microsoft Advertising and Microsoft Audience Network). Schema: { 'mappings': { '<domain>': [<vendor_id>, ...] } }. Community PRs adding entries are welcome — please cite the vendor's official IAB GVL registration ID alongside the change.",
