θaddThemingController

Creates and attaches a ThemingController to the given host element.

This is the preferred way to add theming support to a component. The controller is registered with the host's reactive controller lifecycle and automatically resolves the active theme from an ancestor <igc-theme-provider> context or falls back to the application-wide theme set via configureTheme() .
