# LFS here is per-path, opt-in, and scoped to builder inputs — never a blanket
# rule like `high_dim_data`'s `*.csv` + `*.dta`, which is what puts every one of
# its consumers on the media host.
#
# `lectures/` is the published tree and stays 100% plain git. An LFS-tracked
# path returns HTTP 200 from raw.githubusercontent.com with ~130 bytes of
# pointer text, so a reader gets a parse error rather than a 404 and a
# status-code check reads as green — the failure is silent at both ends.
#
# `sources/` holds builder inputs, is never served, and is the only place an
# LFS object belongs here. Its README is the audit trail for what lives there,
# so it stays plain text.
