Analyses whether a technology shown in a video or described in text can work - extracts every testable claim, checks it against physics with a numeric model (required vs limit), gives a verdict (feasible, feasible within limits, infeasible) and explains the engineering and the physical limits. Then builds an interactive 3D / isometric anatomy page with the anatomy skill - how the system works and where it stops if feasible, or why each key property cannot be achieved if not - plus a Markdown report. Use for 技術可行性、工程原理、物理極限、這可能嗎、真的做得到嗎、科技產品或發表會影片分析, feasibility study, is this physically possible, how does it work, debunk or explain a tech demo.

Turn one line ("a turbofan jet engine", "a mechanical watch", "an LVAD heart pump") into a photoreal, physics based, interactive 3D simulation of that machine in a single HTML file, plus a 20 to 30 second film to post it. Real proportions in metres, real materials (PBR metals, paints, polymers, glass), studio lighting with soft shadows, moving parts driven by a small solver that computes real numbers (thrust, torque, rpm, flow, pressure, efficiency), and modes to explode it, cut it open with clean section caps, x-ray it, slow it down, label it and break it. Use this whenever someone asks to build, simulate, visualise, explain or "show how X works" for any machine, engine, mechanism, device, instrument or piece of hardware, wants an interactive 3D model or a cutaway, or wants a video of a machine for a post, even if they never say "simulation" or "three.js".
