Realistic interactive mid-engine supercar in Three.js

You are a senior real-time 3D artist and Three.js engineer. Build a detailed, realistic, interactive mid-engine supercar in the existing project using Three.js and WebGL. Use the attached image as a visual reference. It shows one original, modern Italian-inspired supercar from front three-quarter, side, and rear three-quarter angles. Keep the design consistent across all views. Do not reproduce the image as a flat plane, billboard, or texture. Build a real 3D car that looks convincing from every angle. Work only inside this project folder. I do not need a mobile view or mobile-specific layout. Focus on the reference image and this prompt. Required workflow: Complete the phases below in order. At the end of every phase, run the project using its existing workflow, inspect the actual rendered result, fix problems, and repeat the checks until the phase passes. Keep the project runnable between phases. Do not mark a phase complete based on code inspection alone when its appearance or behavior needs to be checked in a rendered scene. Make routine implementation choices yourself and continue through all phases without waiting for my review. Phase 0 — Inspect the project Inspect the project structure, Three.js version, rendering setup, conventions, local assets, and run and preview workflow. Decide where the reusable car component belongs and how it should integrate. Reuse suitable local assets and existing patterns. Do not add external dependencies or fetch assets unless the project already has an established workflow for doing so. Check: Confirm that the implementation fits the project architecture and that you know how to launch and inspect the result. Phase 1 — Build the silhouette Create a low, wide, wedge-shaped mid-engine supercar with a short nose, swept windshield, compact two-seat cabin, broad rear shoulders, deep side intakes, and short overhangs. Use approximate real-world scale: 4.5 m long, 2.0 m wide, and 1.2 m tall. Use Y as up, X as left/right, and +Z as forward. Place the origin at the car’s ground-level center, or document a different origin if required by the project. Create actual shaped 3D geometry. Do not leave the result as a crude collection of boxes or floating primitives. Check: Inspect front three-quarter, side, and rear three-quarter views. Correct the silhouette, proportions, wheelbase, and wheel placement. Phase 2 — Build the exterior Create separate body panels with readable gaps around the doors, front storage lid, and rear engine hatch. Add performance tires with visible tread, detailed wheels, brake discs and calipers, headlights, tail lights, indicators, mirrors, window glass, wipers, front splitter, side skirts, rear diffuser, exhaust outlets, grilles, and visible underbody details. Make the side and rear air intakes look functional and integrated into the body. Check: Inspect the same three views. Correct visible intersections, disconnected parts, and missing sur
