Plan a hands-only assembly video with every critical step

Plan a [DURATION] hands-only instructional video for assembling [OBJECT] from [PARTS LIST] and the supplied [ASSEMBLY INSTRUCTIONS]. First provide a numbered shot list with camera angle, hand action, exact visible parts and estimated seconds; then provide narration and captions. Show each irreversible step, orientation and finished-state check without jump-cutting across essential work. Do not invent a torque value, safety rating or manufacturer instruction; mark missing specifications for manual verification rather than inventing them. Keep fingers and tools geometrically consistent across shots. Finish with a viewer checklist and identify any step that cannot be demonstrated from the supplied information.
