fizzgig__empty_state_finder
flags `.map()` over a list with no empty-state guard rendered.
// ai does this over time
the AI builds a list view that looks great with three items. you ship. the first user has zero items. their view is a blank space with no explanation.
// the tool does
JSX-aware heuristic. Looks for .map() in JSX without a surrounding empty-state guard ({items.length === 0 ? <Empty /> : items.map(...)}). Catches the canonical 'list looks broken when there is no data' bug.
// so you can
the empty case is intentional, not accidental. fires before the user with no data hits production.
