Container
Page-level max-width and horizontal centering inside the shell.
The container does not add its own padding — LayoutMain or the host layout's content scroll area should provide responsive padding. Default max-width is 1200px. Common widths: "720px" for focused reading, "900px" for forms and articles, "1200px" for default page content.
Default (1200px)
Standard page width centered in the shell — the default for catalog and app content.
Centered content at 1200px max-width
Narrow form width
Tighter max_width for focused forms or reading columns without changing shell padding.
Focused content at 720px
Custom max width
Override max_width for marketing hero sections or wide data tables.
Form or article width at 900px
