- use `ember-sticky-element` to stick card icons in top left when scrolling
- pass an `headerOffset` down from the `{{gh-editor}}` component through Koenig and the card components so that it can be used for adjustments where necessary
- calculate `headerHeight` in `{{gh-editor}}` any time we change the header class

- sometimes the toolbar was not in a state to measure correctly during `didInsertElement` so the positioning was incorrect
- fixed by re-calculating width/height each time we want to show the toolbar

- ensure we disable `pointer-events` on context menus when hidden so that hidden menus do not interact with the mouse
- add z-index to context menus so that they sit on top of any editor content
- add `relative` positioning to the html card content so the click overlay div doesn't expand outside of the content area

- use Spirit classes for card context menu
- add button and icon class options for context menu items
- add ability to have icon+text for context menu items
- add "Edit" context menu item to markdown and html cards

- add `deleteCard` action to `{{koenig-editor}}` component and pass it through to the component cards
- required modifying the `_deleteCard` behaviour so that it doesn't always try to move the cursor
- use `onLeaveEdit` action from `{{koenig-card}}` in the markdown and html cards to check if their payload is empty and remove the card when exiting edit mode
- fixed `onLeaveEdit` action firing when card first rendered
refs https://github.com/TryGhost/Ghost/issues/9311
- add `hasEditMode` flag to the `{{koenig-card}}` component so that cards without an edit mode (eg, the image card) don't have unnecessary state changes and even listeners
- allow `mousedown` events on cards to passthrough when selecting if the target was an input or textarea so that the cursor can be placed in an input immediately instead of requiring double clicks
no issue
- copy Spirit styles over (eventually these will live in an addon)
- update `ember-cli-build` to output a separate CSS file for Spirit
- update `asset-delivery` addon to output Spirit CSS link
- add `{{kg-style}}` helper for Spirit class names
- update `{{koenig-card}}` and the `{{koenig-card-markdown/html}}` components to use Spirit class names and markup
- replace markdown icon with new version from Spirit

- initial CSS for container card outline, selection state, toolbar, etc
- adds `{{#koenig-card}}` component to be used inside of component card templates to handle the default card container HTML, mouse interactions, etc
- update `{{koenig-card-markdown}}` to use the new `{{koenig-card}}` component
- add render/edit mode views
- focus the textarea when entering edit mode
- updated `{{koenig-editor}}`
- add <kbd>Cmd+Enter</kbd> command to put a selected card into edit mode
- when inserting new cards put them into edit mode immediately
- move edit/select methods out of actions and into normal methods so that timing is easier to reason about
- skip `cursorDidChange` process when cursor changes as a result of a card selection, fixes issues with `selectCard` being triggered multiple times unexpectedly
