Ignore (Edit summary) at top of body block
we’re doing this in teaser instead (see Teaser).
Components should be the default selection but if it isn’t, go to bottom of body block and select components from the Text format dropdown.
Then back to the top of the box to select the first component e.g. text block.
There's no fixed order for body components but our agreed convention is that if we're using a callout block it goes right at the bottom.
