+/**
+ * Severity Enum
+ *
+ * This is a shared enum used to define the severity of different components
+ * (e.g., alert, button, etc.). This makes it easier to reference severity
+ * levels across multiple components, also defining a common concept across
+ * themes.
+ *
+ * Template components must accept all values of this enum as valid input.
+ * However, themes may choose to ignore or bind some values to another style.
+ * For example, a theme might not have an 'Info' colored button. In this case,
+ * the theme's button component must accept 'Info' as a valid input, but it can
+ * map it to the 'Primary' style.
