// `--json` runs write only the JSON to stdout; every log, step, table and warning line goes to stderr (lib/log.ts
// withJsonOutput, wrapped around every command by index.ts). STAR DASH, 2026-10-14: `prices ppp --json` printed log
// lines on stdout before the JSON, so `JSON.parse(stdout)` failed. This runs every command whose module reads --json
// against the fake stores, in a temp project and HOME, and requires stdout to be empty (the command failed or wrote
// nothing) or exactly one JSON document.
