Pick your address in 4 steps: Region → Province → City / Municipality → Barangay. Or use the search box to jump straight to a province, city or barangay (no need to type ñ).
How it works: each level loads ../dist/v1/children/{parentCode}.json only when needed; search loads search-index.json the first time you search. Closing the picker halfway keeps your previous selection; changing a level clears the levels below it.
