MediaContext

Remarks

A surface rather than a screen. A game's UI can be a full window, a split-screen viewport or a world-space panel on the side of a crate, and all three want @media (max-width: …) to mean "this panel", never "the monitor".

⚠ Gamut is the one fact here that is about output rather than layout, and it is still a property of the surface. The honest source for it is ISwapChain.Gamut — what the swapchain was granted — rather than what the display claims to be capable of. A panel rendered into an sRGB swapchain on a P3 monitor can show sRGB, and a stylesheet told otherwise would pick colours that get mapped away again.

⚠ Preferences is a value and not six more parameters here, because those six arrive together from the platform while these five each have a source of their own. See MediaPreferences.
