Can Extensions or CSS modify line spacing?

• I am on the latest Hyper.app version

Issue

I would like to add a few pixels of visual space between the last line of every terminal output and the first line of the next user input command.

To illustrate this visually, my goal is roughly:

To be clear: I do not want to add a carriage return before every user input. I want to add bottom-padding to the last line of each shell output to console.

Xterm.js renders shell text entirely in a canvas object, so I presume it cannot be modified easily with CSS in the .hyper.js file. Is that correct?

I have also seen that I can use TermCSS to modify the layout, but I can't find any documentation explaining what TermCSS is. I also looked at xterm's documentation and I couldn't easily see an affordance for making this happen.

How would you suggest adding a bit of spacing after shell return statements?

Thank you for building Hyper.

Start by tracing Hyper's TermCSS and .hyper.js extension handling, then inspect how xterm.js renders terminal rows in its canvas. Determine whether row spacing can be exposed through the existing extension or CSS mechanisms, and document or implement the smallest supported approach with a reproducible example.
