+3. There must be explicit textual evidence that it reappears across multiple scenes or timelines and needs a consistent visual design. Do not infer future recurrence from common sense.
 4. It must satisfy at least one of the following:
    - characters hold it, use it, fight over it, deliver it, hide it, lose it, or search for it
    - it is a key tool, weapon, artifact, piece of evidence, token, key, or clue carrier

+5. It must also satisfy at least one uniqueness/continuity condition:

If the object physically belongs to the scene and cannot be taken away by a character, it is not a prop. These are "scene states" and should be handled by scene descriptions.

 Example judgements (to calibrate your standard):

 ✅ Extract: an evidence envelope (discovered, handed over, appears in multiple scenes)
 ✅ Extract: a time-manipulating watch worn by the protagonist (core prop, present throughout)
 ✅ Extract: a black SUV driven by the protagonist (cross-scene transport)
+✅ Extract: an ancestral bronze dagger (unique identity, recurring, not replaceable by an ordinary object)
