Can we discuss how you want the funkyheatmap to look with the night theme? I can adapt different elements and use css variables for styles

Rather than hacking the css, we can design the funkyheatmap to be responsive to colour variables.

Here's my two cents:

• in dark mode, all text should be white and rows should alternate between black and dark grey
• in light mode, all text should be black (except header which stays white) and rows should alternate between white and light grey

This could be achieved with --bs-white for header text, --bs-body-color for other text, --bs-body-bg for row background, --bs-button-hover for alternate rows background.
