This is not really an issue, but more of a comment (and personal preference).
First of all: Thanks for creating this theme - it is (in my opinion) the best-looking theme I've come across. I like everything about it!
.. Except.. 🤣 .. the background color for highlighting the current block.
I added the following to my custom.css:
.block-highlight,
.content .selected {
background-color: #272b00;
}
Here are two screenshots before/after:


Just in case someone else is like me and missing a bit of contrast there as well.
