Merge remote-tracking branch 'codeberg/prop/text-input-no-quill'

> We can hand-write markdown for now, as per discussions.
>
> If we have buttons and shortcuts, we'd like them to insert actual markdown into the text stream, and then, as a separate concern, we'd like to render the markdown without changing the text stream (à la Discord). But we're doing none of that now, and it's too high a piece of fruit to pluck today.
