show_usage() {
    cat <<'USAGE'
Usage: ci.sh [options]

Runs the local sequence for the same check IDs enforced by GitHub CI.
Requires uv on PATH when running ruff, ty, or pytest checks.
Local ruff checks repair formatting and autofixable lint before later checks.

Checks (in order):
  suppressions   Ban type ignores and legacy future annotations
  ruff-format    uv run ruff format
  ruff-check     uv run ruff check --fix
  ty             uv run ty check
  pytest         uv run pytest -v --tb=short

Options:
  --only ID                Run only the given check (repeatable)
  --skip ID                Skip the given check (repeatable)
  --dry-run                Print commands without running them.
  --help                   Show this help text.
