Feature request: Dynamic font scaling / zoom with shortcuts

Hi, would be so great if we can adjust the font size like in all browsers and other apps with ctrl/cmd + and - keys.
The use of the css alone is to limited, especially if you changing monitors often, say a laptop and with an external large monitor.

The issue names no files, tests, or entry points. First identify where the macOS editor handles font sizing and keyboard shortcuts, then define the supported zoom behavior and verify that Ctrl/Cmd + and - visibly change the editor text size across display setups.
