# Overnight Europe flow: pbf-base (streets-merged emission) -> verify ->
# painter-cascade faces bake (v2-faces-1, threshold 150ms, buckets 14+16;
# rz15 intentionally falls back to the runtime cascade — the signature
# guard is exact-bucket, so there is no cross-bucket reuse; rz17+ was
# always runtime) -> transmux into Cloudflare-ready .mkmap shards (each
# < 510,000,000 bytes) -> stat-verify every shard under the cap.
#
# Run from the repo root. Reuses the completed pbf-detail store; does NOT
# re-ingest the PBF. Logs progressively to local/maps/europe-overnight.log.
