A built page is full-bleed now, so each band can draw a separator the width of the window, and each
holds its own content to the measure. `[data-content-column]` is therefore no longer one element
wrapping every section — it is one per section, and appending the drop zone to the first match put
"add a section" inside section one.
So it goes in `main`, with its width taken from a column rather than from a constant: the measure is
Tailwind's `max-w-7xl` and this file has no business knowing that. No sections, no column to ask, and
full width is right anyway — there is nothing to line up with.
