Drill: Command palette: ⌘K palette with keyboard nav (↑↓ Enter Esc), grouped results, fuzzy match, footer hints. Must work without mouse.

Interpretation: v3 of the command-palette drill moves to a light warm-paper canvas (both prior versions were dark) for a university library system (Stacks) — catalog, reading rooms, loans. Deep green #0e6b52 is reserved for user intent only (query marks, selection fill, ↵ chip); Inter + JetBrains Mono for call numbers, luminance-stepped neutrals. New mechanics this run: a live fuzzy query seeded in the screenshot state, per-group overflow caps resolved by nested drill-down with breadcrumb, no-results recovery, and a three-state anatomy band.
