More thoughts to get down before the F2F: I am negatively disposed to the idea of allowing the user agent to apply heuristics to adjust the HDR headroom of the page on an element-by-element basis (e.g, limiting HDR headroom for small `img` elements, but automatically increasing it for larger `img` elements that look like they're the "center of attention"). Such a specification would create unpredictable behavior and incompatibility between browsers. Any user agent imposed HDR headroom limits must be applied to the page as a whole. These limits could be imposed because: * power savings are desired * system-wide display settings change * the page is backgrounded (e.g, [this video](https://photos.app.goo.gl/SBBYcWMvHXRjUomG9) shows what Preview does, which is * other user agent specific heuristics -- GitHub Notification of comment by ccameron-chromium Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/11558#issuecomment-2624217485 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
