Describe your idea for an enhancement:

It would be nice to be able to use a different logo for light and dark mode. For example: logo_light.png is used when in light mode, and logo_dark.png is used when in dark mode.

Describe alternatives you've considered:

• Stick to light/dark mode only.
• Use a logo that works in both light and dark mode.

Additional context:

I have a custom logo in greyscale which is hard to see in light mode, so I invert it for light mode. My last OIDC provider allowed me to set custom logos for light / dark mode. It's not a big problem though :)
