mobiler-web 0.11.0

/* mobiler-web default theme — injected by the shell on mount.
 *
 * The web twin of the concrete look the Android (Material 3) and SwiftUI shells
 * decide in code: each style-intent token (TextStyle, Tone, CardStyle, …) maps to
 * a class here. Colors are CSS variables so `Scaffold.dark_mode` flips the whole
 * theme by adding `.theme-dark`. A consuming app may override any of these classes
 * with its own later stylesheet. */
