A bar on every band, Edit / Spacing / Delete above every block, dotted outlines
around blocks and columns, an add-zone at the end. Look at that and you are
looking at the editor, not the page — on the screen whose whole purpose is
judging the page.
A click selects a block and its editor opens in the panel beside the preview,
where every other control now lives. data-fofos-component stays: it is how the
panel writes a draft into the page as somebody types.
Adding a section, adding a block, deleting either and opening a spacing editor
have no door any more. The handlers are untouched and nothing calls them.
