@remix-run/ui

Check the user's current motion preference with prefersReducedMotion() from @remix-run/ui/animation. It returns false during server rendering or when matchMedia is unavailable, so it can be called safely from component render functions as well as browser event handlers.

Server rendering skips setup and render for animation mixins, keyboard and outside-click helpers, typeahead behavior, and popover anchor and focus helpers. Mixins that provide initial attributes, styles, or ARIA props still run on the server.

Bumped @remix-run/* dependencies:

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).

Ignore invalid host prop names and reserved DOM mutation properties during server rendering and client reconciliation. Block javascript: URLs in executable URL attributes while preserving other URL schemes and non-executable attributes. Use the on() mixin for events; the explicit innerHTML API and standard DOM, data-*, aria-*, SVG, and custom-element properties continue to work as before.

Fix duplicated text during hydration when a browser splits long server-rendered text into multiple DOM nodes, including chunks that span adjacent text children (see #11591).

Avoid attaching duplicate event handlers when a client entry imports and renders another client entry, including through fragments and wrapper components. Preserve deferred removal and exit animations when removing nested client entries (see #11844).

Restore the previous named frame from handle.frames.get(name) when a more recently mounted frame with the same name unmounts.
