+/// 1) Pass the "radius" into the constructor, `Component(radius: 12)`.
+/// 2) Set up a theme extension `ComponentThemeExtension(radius: 15)`.
+/// 3) Let `wyatt_ui_kit` "negotiate" and try to find a suitable style in the
+/// flutter theme.
+///

+/// - If the value is mandatory: a hardcoded value in "wyatt_ui_kit" is chosen.
+/// - If not, the style is simply not applied.
