ORIGINAL FOUR-SHOT VISUAL EXERCISE — no inference executed
Project: The Unsent Letter
Plan: 12 seconds total, four shots, no spoken dialogue. Treat durations as editorial intentions; inspect the actual output and supported controls.
Shared continuity: fictional adult courier, blue coat, brass key in right hand, cream envelope on table, window light from frame left, same plain room.
Shot 1 — wide — courier notices envelope on table, key already in right hand
Shot 2 — medium — courier approaches table from screen left, envelope remains closed
Shot 3 — insert — left hand opens envelope while right hand retains key
Shot 4 — close view — courier reads silently, then looks toward screen right, key stays in right hand
No new character, costume change, location jump or extra envelope.
Acceptance: inspect order, actual cuts, key-hand assignment, envelope state, light direction and ending. This prose is not an API payload. Translate into the selected interface's supported controls.
