## Previously published material

The repository through commit `7e949cb2ef48660cfb45c1e82d73387b2c39a74c` was published with MIT for code, scripts and written instructions, and CC BY 4.0 for visual assets. Both license files were introduced in the initial commit `07918b029245b199b0a69ac1b2be808284856ebb`.

Historical license records:

This change does not revoke rights already granted under those licenses. Previously licensed, unchanged material may remain usable under the historical licenses. Replacing license notices alone does not make those historical copies or permissions noncommercial-only. New contributions and genuinely new material offered under this policy follow the current noncommercial terms.
