Preserve client-owned attributes during frame reloads with data-rmx-preserve-attrs="class data-theme" on any matched element, including <html> and <body> (see #11809). The named attributes keep their live values or absence while other attributes and children reconcile normally. The incoming HTML controls the list; clearing it or removing a name returns those attributes to normal reconciliation.

Allow client entry props to use ordinary interfaces, including nested objects whose properties are all optional (see #11918).

Send X-Remix-Frame: true from the default browser resolver for all frame loads, including top-frame navigation and reloads. Named frames also send X-Remix-Target, allowing handlers to identify and target frame requests consistently across browser and server rendering (see #11941).

Treat marker-less HTML that starts with a doctype or <html> as a document reload, so pages rendered with renderToString can be navigated by the client runtime (see #11808).
