Crayons

Note: Real-world scale: the box is 0.065 m wide × 0.024 m deep, with a 0.058 m back wall and a 0.050 m front wall. Crayons are 0.090 m long and 0.00975 m across at the default toyEra. The whole model is 0.102 m tall to the tallest back-row tip. 2076 triangles, 26 meshes, no animation clip. Origin is the bottom centre of the footprint, which includes the loose crayon. The box floor and the loose crayon's wrapper bands rest at exactly y = 0, and the front faces +Z. Material names are the Toy Box palette colour names verbatim (e.g. 'blue' box, 'yellow' band, 'soot black' wrapper bands), so the kit recolours by name; the design role is on material.userData.role. The exporter writes one material copy per mesh, which is why a lint reports 26 materials for 9 distinct colours. All four params are build-time knobs that rebuild the geometry. toyEra switches below 0.34 from a printed blue box with a yellow band and bright crayons to a vintage kraft box ('wood' with a 'dark wood' band) with a muted crayon set, and it continuously grows crayon girth from a slim 8 mm stick (0) to a chunky 11.5 mm toddler crayon (1). perRow sets 3–6 crayons per row (6–12 in the box), and the box width follows it, so per-crayon part ids beyond _f3/_b3 exist only when perRow is high enough. wear shortens and blunts crayons with a fixed seed. flapOpen swings the tuck flap from just past upright (0) to folded well back (1). Part ids use the 'crayons.' prefix because the kit's part-id grammar does not allow hyphens. The viewer's ground disc and lights are staging only and sit outside exportGLB({scope:'model'}). glb-lint reports 0 errors and 6 heuristic warnings, all expected. Material count and duplicate materials come from the per-mesh copies. Non-indexed primitives are deliberate: per-face normals keep the model flat-shaded in every engine. Sibling overlaps are the embedded joins: band on box, riser in box, wrapper rings sunk into sleeves. The 'detached' flap is hinged into the back-wall top as the only child of its pivot group. The 0.1 m height is compared against the flat-lowpoly 1 m reference. The lint's overall verdict reads UNVERIFIED only because no requirements contract was supplied. Known capture artefact: the headless capture renderer draws faint 1 px lines on the box front in the straight-on front view, where crayon and inner-wall edges sit behind the card. It is not geometry (≥ 0.6 mm clearance), not shadows, and not depth precision (all three were ruled out by bisection), and it does not appear in the hero.
