# Indentation was the one formatting rule this repo had no gate for. The Rust side has
# `cargo fmt --check` in ci.yml, but the TypeScript side has ESLint, which carries no formatting
# rules here on purpose: adding Prettier would put a new package into a tree that deliberately runs
# `minimumReleaseAge` and `blockExoticSubdeps`, for a problem an editor setting already solves.
#
# The drift this exists to stop was real rather than hypothetical. Every file under `src/` uses four
# spaces except `src/main.tsx`, which was scaffolded with two and stayed that way because nothing
# read it.
