WebKit adds name-only @container scoping

This is a small syntax change with outsized ergonomics: container queries stop looking like breakpoint math and start behaving like a native scoping primitive.

• –It removes the awkward “always-true” size check pattern, so named containers read more like intent than workaround
• –Compared with BEM, nesting, or CSS modules, this keeps component boundaries explicit without inflating specificity
• –The feature is still Safari-only, so teams will need progressive enhancement or fallback rules for Chrome and Firefox
• –For design systems, this is especially useful when the file name or component name should map directly to style scope
• –MDN still frames named containers around size queries, so this update is a meaningful simplification on top of an existing concept
