desk rendering(pc, mouse, monitor, keyboard) with browser OS on monitor

you can use html, CSS, JS, 3js and any other libraries you may wish to use in a single HTML file.
it should run on most devices permanently or in other words make it optimized.
it shall be self-contained and shouldn't require any precautionary steps other than opening the html file in a browser
Do not worry about mobile compatability, it will be run on a windows PC(both 10 & 11)
first, using 3JS or other 3d rendering libraries, render a PC(a monitor, keyboard, mouse, and the actual PC), do not add RGB to the pc or other bright lights for visibility(also don't make it too dark/add excessive fog).
You should able to press the keys(using the mouse, or by pressing the keys on the real keyboard) and they should appear as being pressed, the mouse should be moved by pressing and holding it and moving around using the mouse pointer.
On the monitor, there should be a OS types system(macOS style, not a full on clone but the style with 5 apps and 2 2d games like tetries and snake), when you press keys on the virtual keyboard and move the virtual mouse, it should be reflected on the monitor.

You should be able to press "Z" to zoom into the monitor, here have the OS displayed in full screen and de-render the keyborad,mouse and pc fo performence and "Y" to again come out and see the full desk.
when you open it, it should be a dark screen and press any button to start, when you press escape you should come back to this screen.
