There is just one thing we need to fix before merging: Right now, the tour tooltips use the default react-joyride styles (rounded corners, soft shadows). This breaks the brutalist, sharp-edged, neon aesthetic of the app.

Could you please pass a styles prop to the component to force it into our brutalist theme?
Once it looks boxy and brutalist, I will approve and merge!

[priiyanshu-kumar]

Updated the onboarding tour styles to match the brutalist theme with sharp edges, bold borders, and removed rounded corners/shadows.
