# Usage:
#   ./scripts/prepare-pbf.sh /path/to/region.osm.pbf
#   ./scripts/prepare-pbf.sh /path/to/OSRM/data/us-latest.osm.pbf --symlink
#
# After this, set NOMINATIM_PBF_FILE in .env (default region.osm.pbf) and:
#   docker compose up -d
#
# Shares the PBF with OSRM only — never copy/use .osrm* graph files here.
