/// Small-phone layout guard. A Flutter `RenderFlex overflowed` (a clipped title,
/// a save button pushed off a non-scrolling column, a Row too wide) is reported
/// as an error and FAILS the test — so pumping each screen at a tiny viewport,
/// in the languages whose text runs longest (es/pt/ast), catches exactly the
/// "the save button / title isn't fully visible on a small phone" reports.
///
/// FULL SCREENS ONLY. Modal bottom sheets (quick-add, the lot editor) are NOT
/// checked here: `showModalBottomSheet` gets an unbounded height in a widget
/// test, which fabricates a huge false overflow. Those sheets already wrap their
/// body in a `SingleChildScrollView`, so their save buttons stay reachable;
/// verify them on a real small device.
