Improve UX of notes #36
Description
The current note design in page embed isn't obviously clickable and does a poor job of highlighting the excerpt once it's been opened. Review UX with the following goals:
- Make them more obvious and discoverable so it's clear they're interactive, not just decoration/design on the original source page
- Explore how to make them visible when a small note on a small embed is opened
- Explore how to navigate through notes sequentially
