Function init_component_theme 

pub fn init_component_theme(initial: Scheme, scale: f32, cx: &mut App) -> bool

Enable the Component theme bridge after gpui_kit::init, before opening a window or returning its content builder. Initialize from the final startup palette and scale, including capture overrides, so the first Root preparation sees the correct colors and rem size. Returns false when Component is absent. No transition is started for this initial paint. The bridge owns the sans family from Material’s current body type scale, its base size and projected colors. The projection does not own monospace fonts or unrelated geometry; Component mode configurations retain their normal behavior for those fields.
