Cast

Colour modes for the control panel.

• A theme is a stylesheet that redeclares the CSS custom properties that Craft already ships in ThemeAsset.
• Per user: so everyone chooses their own from Account → Preferences, or you pin the whole team to one.
• Your own themes: drop a .css file in cast-themes/ and it's automatically registered. Plugins and modules can register in code.

Cast is in beta. The theme APIs are settled (Themes::EVENT_REGISTER_THEMES and the cast-themes/ file format won't change before 1.0.0) but the plugin's own settings may still move.
