+
+    The OpenAI client that Recraft uses has a bizarre way of serializing lists:
+
+    It does NOT keep track of indeces of each list, so for background_color, that must be serialized as:
+        'background_color[rgb][]' = [0, 0, 255]
+    where the array is assigned to a key that has '[]' at the end, to signal it's an array.
+
+    This has the consequence of nested lists having the exact same key, forcing arrays to merge; all colors inputs fall under the same key:
+        if 1 color  -> 'controls[colors][][rgb][]' = [0, 0, 255]
+        if 2 colors -> 'controls[colors][][rgb][]' = [0, 0, 255, 255, 0, 0]

+        etc.
+    Whoever made this serialization up at OpenAI added the constraint that lists must be of uniform length on objects of same 'type'.
