# DuetOS is primarily Linux-hosted; the build is driven by POSIX
# shell scripts under tools/ whose shebangs MUST be LF (a CRLF
# shebang makes the kernel `env: 'bash\r'` and the whole codegen
# step fails). Without this file, a Windows checkout with the
# default core.autocrlf=true mangles every text file to CRLF,
# breaking the build and round-tripping CRLF back into the repo
# (which clang-format CI then rejects). Force LF for all text and
# normalize on commit. See CLAUDE.md "Style: LF line endings
# everywhere".

# Default: treat as text, normalize to LF in the repo, check out LF.

# Source / build / docs — always LF, never CRLF.
