Add dark mode to the Aha! interface Merged

What is the challenge?

The current interface is mostly white. I have a visual impairment that makes viewing the Aha! interface painful. I work around this by forcing my browser to invert colors, but this solution is imperfect for many reasons - I need to enable the setting every time I launch the browser, and the design/contrast in this mode isn't up to WCAG standards so some text or features aren't legible in dark mode.

What is the impact?

Improved readability and accessibility for Aha! users with visual impairments

Describe your idea

Design a dark mode color scheme and enable a toggle for dark mode on/off in the personal settings and/or in the top menu across the site so users can enable dark mode easily when that view benefits them.
