Blender runs on the server; your tablet just watches

Blender's viewport wants more memory than your tablet will ever have. So Blender runs in a container on a bare metal box with real cores and serious RAM, and display-2 streams it to your browser with H264 encoding.

You orbit the model from the couch. You kick off a long render, close the tab, and check progress from your phone at dinner: the desktop kept running, you just stopped looking at it. Reconnect, and you see current state.

The 3D workstation used to be a purchase: a tower, a desk, a room. Now it's a rented box and a URL.

The heavy machine is rented; the screen is whatever you're holding.
