# SHA of devnen/Chatterbox-TTS-Server. Bump + rebuild when you want
# upstream wrapper updates. Use the FULL 40-char SHA — docker buildx's
# git source resolver doesn't accept short hashes. Pinning to a SHA
# (rather than `main`) protects against upstream churn — the previous
# `main` value broke when devnen restructured docker/ paths in repo.

#                                         ~3.5 GB fp16, slower but with
