+/**
+ * Qualifies classes that provide display-specific info for shade window components.
+ *
+ * The Shade window can be moved between displays with different characteristics (e.g., density,
+ * size). This annotation ensures that components within the shade window use the correct context
+ * and resources for the display they are currently on.
+ *
+ * Classes annotated with `@ShadeDisplayAware` (e.g., 'Context`, `Resources`, `LayoutInflater`,
+ * `ConfigurationController`) will be dynamically updated to reflect the current display's
+ * configuration. This ensures consistent rendering even when the shade window is moved to an
+ * external display.
