Requires every data surface to explicitly cover empty, loading, and error states (never a silent blank default), and applies preattentive-processing rules to tables and dataviz (right-aligned numbers, sticky headers, bar/line over pie, consistent category-to-color mapping).

Sources craft from the local corpus's two application interfaces (reve, linear) — no sector browsing — and declares the three reproduced elements (Je reproduis) that design-review verdicts.
