Notes / Gotchas

CTB and NWFB merged operations in 2021 but remain separate API entities
Cross-harbour tunnel routes operated by CTB/NWFB connect Kowloon to HK Island — include for cross-harbour visitor flow
Bus stop coordinates endpoint requires individual stop ID lookup — batch requests needed for full spatial dataset
