* Add primary-color to Tailwind, driven by themeColor setting

* Get rid of most uses of "energy" colors

* Change out the rest of the energy colors

* Tweak NetworkHealthIndicator light mode checkmarks

* Handful of other CSS tweaks while I'm here:
- remove the AppHeader bg and border
- pane margins
- better dark mode button styles

* Make Zoo logomark a badge

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu)

* Re-run CI post-snapshots

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu)
