The planner board now works the way a board should. Drag a card from Drafts to Needs approval to send it for review, or across to Approved and Scheduled as it moves along.
The board knows what is allowed. A post with no content cannot be dropped into a column that would schedule it, and a post that is mid-publish stays put.
Scheduling around review
Scheduling a post that has not been approved yet asks you to confirm first, and it asks the same way whether you are in the composer, on the planner, or on the schedule page.
When a reviewer asks for changes, their note now lands as a comment on the draft, so the reason sits next to the words it is about.
A gated post that misses its slot now moves back to drafts with a note about the missed slot, instead of sitting on the board with a time that has already passed.
