When a source constrains its content to a max-width the theme has no preset for, should the converter snap to the nearest fixed preset, emit a per-section custom width, or tokenize container widths into a reusable library?
The question: A converted "About" section used the source's container-narrow class
(max-width: 64rem). The section shortcode's Container Width control offered only fixed presets
— Narrow 768 / Medium 896 / Wide 1024 / Custom. 64rem is 1024px, so this one mapped to Wide — but
the general problem stood: when a site uses a container width the theme has no named slot for
(and reuses it across many pages), how should the converter represent it so the result is faithful
and reusable, not a value copy-pasted onto every section?
