MenuFrame

public sealed record MenuFrame : IEquatable<MenuFrame>

One fully composed, ready to draw snapshot of a menu for a single player.

The frame is the boundary between menu logic and rendering. By the time a renderer sees it, component selection, focus and paging have already been resolved, so a renderer only has to turn nodes into output.
