- the background color of the button was incorrectly applied to the original accent colour rather than the adjusted accent color
- added adjustment of text color on hover too in case it went outside of a visible range
refs https://github.com/TryGhost/Team/issues/928
- we want to make use of the same color adjustments and contrast selection for accent colors we use in Admin on the server-side for emails so utility functions have been extracted to an external package

- usage of `color` was incorrect resulting in an infinite loop because the color was not being changed on each iteration
- `Color().lightness()` adjusts via percentage not exact number
- `Color().l()` does not return lightness
refs https://github.com/TryGhost/Team/issues/928
- it's possible to set a button with no content in the CTA card but the auto-removal when exiting edit mode was only checking for presence of content
- updated to only remove the card when no content, button text, or button url has been set
refs https://github.com/TryGhost/Team/issues/928
- switched to using `color` for color conversion and adjustments rather than maintaining our own limited utils (preparation to extract our own utils to separate library)
- changed contrast threshold for yiq-based contrast adjustment from `128` to `186` to match Portal's current behaviour

- Some limit errors don't contain a "details" property, in those cases the code should still execute instead of throwing an errors!

- the `email-cta` card can be segmented so only free or paid members can see the content, it should be possible for authors to preview what that will look like in either case

- When an error is returned from the server during a CSV import and it's because of the email freeze the import modal error has to show a special header along with error message

- button should be visible when not editing if both text and url are set
- added container for the content section so other links aren't clickable
- added tooltip to button so button url can be checked without having to go into edit mode
refs https://github.com/TryGhost/Team/issues/927
- added CTA `button and url inputs to email-cta card
- added `textColorForBackgroundColor` color util and used it to add a white/black text color variable that can be used when the accent color is used as a background color
- added `{{hex-adjust}}` helper for modifying lightness and saturation of a hex color
- adjusted inline power-select dropdown styling
refs https://github.com/TryGhost/Team/issues/927
- allows for more information about a card to be shown when hovering over the indicator to the left of the card's section in the editor
refs https://github.com/TryGhost/Team/issues/927
- we'll soon need access to adjusted accent colours outside of the application controller so they're now available on the `ui` service
refs https://github.com/TryGhost/Team/issues/931
- prototype button has served it's purpose in answering questions and is no longer being used
- groundwork is left in place for future component-based atoms
refs https://github.com/TryGhost/Team/issues/931
- adds handling for component atoms
- add prototype button atom to test atom behaviour
- add `Cmd+Shift+B` keyboard shortcut to create a dummy button atom when the `emailCardSegments` feature is enabled
refs https://github.com/TryGhost/Team/issues/926
- updated `<KoenigEditor>` so it creates default card payloads as TrackedObject instances so that getters in glimmer component based cards can track changes to payload properties
- added dropdown free/paid selector to email-cta card that sets the `segment` payload property to the respective filter
- updated design to show the footer outside of edit mode too so that the selected segment is always visible
