Dark mode support #81
Description
Is your feature request related to a problem? Please describe.
I like how this theme looks, however it can be rather jarring to view it when the rest of a system and most other websites open are in dark mode.

Dark mode support
Additional context
Related to #59, however making a dedicated feature request issue here since dark mode support doesn't necessarily require customisable colours (although it helps significantly) and for easier tracking.
