Suggest sound effects for takes (costs credits)

For each take, the AI reads its exact frames (up to 8 at even steps over what plays of it, as one numbered sheet) with its action prompt, the moments it runs between, their light and weather, who is there, the place and what is said, and proposes small physical sounds that happen on screen, each at its second of the clip: {at_s, duration_s, name, prompt, level, rise?, why?} (prompt is a concise sound-effect prompt; level 0.6 soft, 1 medium, 1.4 loud; rise dB it starts under for a sound coming toward the camera). Short, matched to the visible motion, never music, a voice or an ambience the place already has, at most 2 in any 4 seconds, the same sound at most twice. take_ids names the takes; absent, every take in use with a clip and no effects yet. Costs credits: one scan per take read (see /v1/pricing), checked before each call and charged only after an answer with a suggestion, through your token so its daily cap applies. Quote first with dry_run: true. The proposal is NOT saved: send what you keep (edited or not) to POST /v1/storyboards/{id}/effects. A storyboard whose owner approves agent spending answers 403 except for the quote.
