Pressing the button drawn inside the page opens a dialog: a name, and a choice between one column and
two, then Create section. The row lands in the database and the frame re-renders to show it.
The layouts are DRAWN rather than named. "One column" is words for a shape, and a shape is faster to
recognise than to read; the words stay underneath for anybody the picture does not reach.
The name is asked for and not generated. It never appears on the site — it exists so a page of eight
bands is navigable, and "Section 4" tells nobody anything, which is exactly the state a generated name
would leave every page in. Asked at the only moment somebody knows what they are about to build.
The frame is remounted after a write rather than the admin drawing the new band itself. The site
renders from the database; the admin does not know how to render a page, and if it learnt it would be
a second implementation of the very thing this preview exists to avoid.
The canvas now finds the empty-page placeholder by its `data-page-empty` marker instead of taking
`firstElementChild`. That was right for exactly as long as an empty page was the only kind — the moment
a page has a section, the first child IS that section, and it would have hidden the thing being edited.
