home page feedback

[crcn]

• be more clear about what scoped CSS is on home page
• code coverage GIF is unclear
  • Maybe create Figma diagram that goes through more basic visual - something that feels like unit tests for visual UI
• combine multiple code examples in tabs that can be cycled through - use embedded REPL
• without annotations, things are moving a bit too quickly
  • possibly annotate designer + include screenshots of measurement tools - use something like guide
