Use Blender (bpy + Cycles, already installed) to build our galaxy, the Milky Way, and render a 10-second cinematic flythrough of it. The galaxy: a barred spiral the way astronomers map it today. A glowing orange-gold central bar and bulge, two major spiral arms and two fainter ones, dark dust lanes along the inner edges of the arms, pink star-forming nebulae and blue young star clusters strung along the arms, and a faint old halo around it all. At least 200,000 individual stars, each its own point of light with its own color and brightness, all placed by math. No images, no downloaded textures, no HDRIs, no stock assets. The shot: 0 to 3 s, the whole galaxy face-on from far above, turning slowly. 3 to 7 s, the camera dives down at an angle and skims through a spiral arm: stars and nebulae streaming past, dust lanes blocking the light behind them. 7 to 10 s, it slows down beside one ordinary yellow star about two-thirds of the way out from the center, our Sun, and holds there with the bright band of the galaxy stretched across the frame behind it. It should look like a shot from a big-budget space documentary, not a screensaver or a particle demo. Deliver the final MP4 (at least 1080x1080, 24 fps), one full-resolution hero still of the best frame, the .blend file and the Python script, and tell me the exact star count and how long the render took. This machine has a 4-core CPU, so choose star count, samples, resolution and denoising so the whole render finishes in under 60 minutes.
