8	`@mapbox/vector-tile` 3.0.0 and `pbf` 5.1.2 -- on 2026-09-23:

10	- `ocean_ranges.bin`: every byte range the `pmtiles` reader read to fetch two open-ocean
11	tiles, as `[u64 offset \| u32 length \| bytes]*`, little-endian: the header and root
12	directory, their two leaf directories and the one tile content they share.
13	- `expect.json`: the archive header as that reader parsed it, fifty tiles with their Hilbert
14	ids and the length and FNV-1a-64 of each decompressed tile, and ids converted both ways.
15	- `<z>_<x>_<y>.mvt` and `.json.gz`: two small tiles, decompressed, and the reference
16	decoder's reading of them (layers, features, ids, types, properties, geometry).
17	- `sample.pmtiles`: a small archive written by the reference Python writer (`pmtiles`
18	3.8.1) with `make_sample.py`, holding the two small tiles above and the open-ocean tile
19	addressed as a run of three, all gzipped: a real archive not written by this library.
