A perforated faceplate with 18 inner, 12 slotted, and 72 outer cutouts arranged in radial symmetry, divided by six cruciform ribs and framed by a chunky outer ring. All openings are carved in a single sketch and extruded as one watertight body, with the tracery as through-holes. Inner and outer bands use `@floor` and `@mod` on `$index` to compute cluster-then-petal positions from a single `qty`.
