Theme that follows the OS-level light / dark setting.

At call time theme/0 reads Dala.Theme.color_scheme/0 and returns Dala.Theme.Light.theme/0 or Dala.Theme.Dark.theme/0. Built for outdoor working users — sun-readable in daytime, eye-friendly at night.

Usage

defmodule MyApp do
  use Dala.App, theme: Dala.Theme.Adaptive
end

Reactive switching

Dala.Theme.set/1 snapshots the theme at call time, so toggling the OS appearance after the app has started does not auto-update the rendered theme. To re-evaluate, call Dala.Theme.set(Dala.Theme.Adaptive) again (e.g. in response to a foreground / lifecycle event, or after a planned :color_scheme_changed device event in a future version).
