+// Cache defines a generic interface for a key-value storage with type constraints on keys and values.
+// The keys must be of a type that supports comparison.
+// Add inserts a new key-value pair, potentially evicting an item if necessary.
+// Get retrieves a value associated with the given key, returning a boolean to indicate if the key was found.
+// Purge clears all items from the cache.
