// selector visibility rule (only when profiles.length > 1) plus its
// APPLY_PROFILE_DEFAULTS path, the sandbox toggle (which is disabled
// when Docker is unavailable), and the Advanced section's extra-env /
// extra-args inputs. Profile-defaults seeding on mount is exercised by
// the unit tests on the reducer; here we test the picker-driven UI path.
