iOS experiences
- Time picker: The iOS time-picker sheet is presented by UIKit above the WKWebView (the engine behind PWAs/home-screen apps), and in that context it reads only the OS-level
prefers-color-scheme— none of the standard web overrides (JS inlinecolor-schemestyle, color-scheme CSS,color-schememeta) reach it. This appears to be a genuine WebKit/PWA limitation with no fix available from the web side. The only way to make the time picker honor the app’s own theme is to stop using the native<input type="time">and render the picker UI yourself.
