Thanks for the update, that helps. Two thoughts:
- Instead of ['flex-basis' becomes ''content''.], maybe say [the used
value for 'flex-basis' is "content".]?

- To clarify, in https://drafts.csswg.org/css-flexbox/#algo-main-item
"or depends on its available size" is meant to catch min-content et
al? (by the way, what about fill-available, is that definite?)
