Enum ThemeSource 

pub enum ThemeSource {
    Derived,
    DerivedWithAccent(Color),
    Pinned(Theme),
}

Where a Core’s theme comes from, re-read at the start of every frame. Derived is the default.

Pinned makes this as big as a whole Theme, which is the point: there is one of these per window, read once a frame, and boxing it to save three hundred bytes would cost the Copy that lets a view hold the answer without borrowing the core.

Variants

Derived

Theme::from_system on whatever env.system currently says, so the app follows the OS without writing a line about it.

DerivedWithAccent(Color)

The OS’s appearance, this accent. What an app with a brand colour wants: it should still go light when the user does.

Pinned(Theme)

Exactly this, following nothing.
