# `Mob.Theme.Adaptive`
[🔗](https://github.com/genericjam/mob/blob/master/lib/mob/theme/adaptive.ex#L1)

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

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

## Usage

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

## Reactive switching

`Mob.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 `Mob.Theme.set(Mob.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).

# `theme`

```elixir
@spec theme() :: Mob.Theme.t()
```

Returns the Light or Dark theme struct based on the current OS appearance.
