# Enforce LF line endings in the working tree for all platforms.
#
# Without this file, Windows developers with `core.autocrlf=true` (the default)
# get CRLF in their working tree, which conflicts with Biome's
# `formatter.lineEnding: "lf"` config and causes `npm run format:check` to
# report spurious errors (the index stores LF correctly; only the local
# working tree is wrong).
#
# `* text=auto eol=lf` tells Git: detect text files automatically, and force
# LF in the working tree regardless of the platform's autocrlf setting.
#
# This file is the canonical override for the platform-default behavior.
# Added in TP-193 fold (post-merge format-pass cleanup).

* text=auto eol=lf

# Explicit overrides for binary file types (defensive — autodetection usually
# handles these correctly, but explicit declaration prevents corner cases).
