Nested docs categories with smarter navigation
Improvements
- Docs now support deeper category nesting, with breadcrumbs, sidebar, and prev/next navigation that traverse the full tree.
- Docs categories without their own page now show a list of their child pages automatically.
- The marketing homepage now shows for everyone instead of redirecting signed-in users to the research dashboard.
- Simplified the mobile menu by removing the non-interactive Channels and Automations sections and giving "Get Started" a more prominent button style.
Fixes
- Fixed invisible UI elements across marketing pages — badges, gradients, workflow diagrams, feature cards, and story-player effects — caused by bad theme color values.
- Fixed step indicators and connector lines on use-case detail pages so they render and stay aligned in their column.
