Boundary to investigate

Review hypothesis. No visibility changes or removal decisions have been made.

First 0.1 alpha release; the API may change. Verified on Apple M-series, Intel Iris Xe (Fedora 44, Windows 11) and Arc 140T (Windows 11); Linux shows wide content as an sRGB preview. The engine must use the compositor’s GPU; automatic adapter matching is not available. AMD and NVIDIA are untested. Evidence in issue #198.
