No Sidebar
With both rails gone the article takes the full container width — here softened to a centered ten-column measure so long lines of text stay comfortable to read. This is the layout for pages where nothing should compete with the content: landing pages, long-form writing, and detail pages that carry their own weight.
Full width doesn't mean full-width paragraphs. Long text lines tire readers, so this page still narrows to ten columns even without a rail eating the other two — a photo, a table, or a gallery can still break out to the container edge on the pages that need it.
Mixing layouts across a site is the whole point of this set: a full-width page like this one, an article with a right rail, documentation with a left rail — all sharing the same navbar, page banner, and footer, so switching between them never feels like leaving the template. Pick per page, not per site, and start here whenever no rail earns its keep yet.
