do this for B2 plane: 2x2 GRID — Famous Invention Study
<instructions: input = [ANY INVENTION]>

ANALYZE:
Infer the invention’s patentable features, functional subsystems, internal architecture, and mechanical logic.

$ patentscene =
A 3D “ghosted” exploded-view diagram where the invention’s layers float apart in space, connected by dotted leader lines and numbered callouts.

Function Draw($patentscene){
    <technical_spec>
        STYLE: 19th–20th century Patent Drawing / Technical Blueprint.
        FORMAT: 2×2 grid, each quadrant = one FIGURE (FIG.1–FIG.4).
        COLOR: Cyanotype Blue OR Monochrome Black Ink.
        LINEWORK: Precision vector drafting lines; cross‑hatching for shading; stipple for material density.
        LABELING: Engineering callouts, figure titles, part numbers, dotted leader lines.
        CAMERA: Orthographic projection (no perspective distortion).
    </technical_spec>

    <layer_logic>
        * Layer 1: OUTER SHELL  
          (casing, housing, aerodynamic skin, enclosure panels)

        * Layer 2: STRUCTURAL FRAME  
          (chassis, spars, ribs, brackets, load-bearing members)

        * Layer 3: FUNCTIONAL SYSTEMS  
          (motors, gears, coils, optics, circuits, combustion chambers, etc.)

       * Layer 4: MICRO‑COMPONENTS  
          (wiring, fasteners, bearings, sensors, filaments, valves)

        * Each layer floats apart in Z‑space with consistent spacing.
        * Maintain mechanical plausibility and internal routing logic.
    </layer_logic>

    <transformation>
        * Convert the invention into a ghosted exploded-view with transparent outer layers.
        * Add callout numbers + concise engineering labels.
        * Add FIGURE TITLES per quadrant:
            FIG.1 — External Form & Shell
            FIG.2 — Structural Framework
            FIG.3 — Functional Mechanisms
            FIG.4 — Micro‑Components & Internal Routing
        * Preserve instructional clarity, drafting precision, and patent‑sheet readability.
        * No stylization beyond blueprint/patent conventions.
    </transformation>
