# Pull the tidal atlas dataset at build time (MARC PREVIMER + SHOM Atlas C2D).
# The dataset is private so we need an HF token with read access. On HF
# Spaces, define the secret in Settings -> Variables and secrets -> Secrets:
#   HF_TOKEN  (User Access Token with read scope on Qdonnars/openwind-tidal-atlas)
# Runtime reads MARC subdirs via MARC_ATLAS_DIR and the SHOM Parquet+JSON via
# SHOM_C2D_DIR; both point at the same shared directory because the layout
# inside the dataset places SHOM artefacts at root next to the per-atlas MARC
# subdirs. The fetch script falls back gracefully (empty dir, runtime uses
# Open-Meteo SMOC only) when the secret is absent.
