  "limits": [
    "Surface curvature and cabin dimensions estimated",
    "Seven gauge scales, neutral editable counters and two warning symbols source-informed; exact 1987 fitment, remaining warning legends, physical size, typography and calibration incomplete",
    "Static zero or unpowered parked needles; no live instrument simulation",
    "Estimated reversible headlamp and door studies; simplified editable inner shells, jambs, hinges, latches and pull controls are not factory-measured hardware",
    "Bounded seven-pose door sweep records unresolved seal-release and coarse hinge-envelope contacts; it is not a production-clearance certification",
    "Rear engine cover, folding stay, underside ribs, paired rear-lock hardware and exposed engine-bay layout are authored studies; hinge coordinates, pose, component dimensions and kinematics are not factory measured",
    "Eight-pose rear-cover clearance sweep found no unexpected overlap among the tested structural objects; closure, hinge and coarse rear-attachment envelopes remain tolerated and rear-fascia duplicates are excluded, so this is not production-clearance certification",
    "Twin bonnet ducts are actual recessed geometry with four editable width/depth stations, but the 70–210 mm authored widths, 4–38 mm ramp depths, plan shape and edge sections are photographic estimates based partly on a later 1989 European hood",
    "Laminated-windscreen and Perspex PBR materials are now independently editable; their scalar values are authoring baselines, not measurements of a 1987 launch car",
    "Paired lower rear side volumes and the recessed large/small/large triple exhaust relationship are source-informed; the 245 mm depth, 42 mm rear lip and 90/64/90 mm outlet diameters are photographic/form estimates, and the backing is not a complete silencer model",
    "Pass 23's bounded C1 rear-body fairing reaches a 10 mm local correction and returns to zero at its boundaries; the value is a photographic/form estimate without a factory body section, scan or calibrated source-camera solution",
    "No front-cover articulation, complete engine assembly, authentic sound or browser/device validation"
