The user is asking for a self-contained HTML file containing inline SVG. Build a scene with appropriate layering. Create a nice SVG: sky gradient, sun in the top-left, two clouds, house on the right in the background, ground line, a forklift with mast and forks, and on the forks three stacked servers with indicator lights, a dog wearing a helmet sitting in the seat holding a steering wheel, and in the bottom-right a model name "Claude" signature.

Design coordinates: viewBox 0 0 800 500. Ground at y=420 (flat ground rectangle from 420 to 500).

Forklift: body around x=300-450, wheels at cx=330, cx=440, cy=420, r=30? Wheels touching the ground means wheel bottom y=420, i.e., cy=420, wheel bottom y=420, so cy = 420 - r... wheel bottom = ground line 420 → cy = 420 - r? No, wheel bottom touching ground → cy + r = 420 → cy = 390, r=30.

Forklift body: rectangle x=290, y=300, width=180, height=70 (bottom is 370). Wheels are cx=320 and cx=440, cy=390, r=30.

Mast: vertical rails at x=480, y=200 to 420. Forks at the front (right side): fork carriage at x=490, forks extending right at y=340, fork tines from x=490 to x=570. Servers stacked on the forks: server rack? "rack of three stacked servers" — draw a rack frame at x=500 to x=580 with three server units, sitting on the fork tips (fork top y=340). Each server height about 30: rack from y=230 to y=340. Server: rectangle x=502, width=75, height=30, with gaps. Indicator lights: small green/red/amber circles.

Dog: sitting in driver's seat — seat backrest behind dog at x~300. Dog body around x=340-390, head above, helmet on head. Steering wheel on the front of the dog at x~430, dog's front paws reach the wheel.

Layer order: house, sun, clouds → sky comes first. Ground. Forklift: seat, dog body, then body in front? More simply: seat, dog, then draw the body lower part covering the dog's lower part? The dog sits on top of the body. Draw forklift body, wheels, then draw dog on top, helmet on head, mast and forks, servers in front of or behind the mast.

Order: sky background, sun, clouds, house, ground, forklift body, wheels, mast, forks, seat, dog body, front paw to steering wheel, head, ears, snout, helmet, servers on forks (forks behind servers? Servers sit on forks — draw forks then draw servers on top so fork tips show under the servers).

Signature: small text "Claude" in the bottom-right.

Write HTML with embedded SVG. Keep it reasonably tidy.
