Price, then render, one pitch deck chapter again.

The writer's priced retake: a new 480p take of one call (callId) or of every call of the chapter. A chapter whose plan changed since it rendered (or that never rendered, such as one inserted in review) is recompiled first (free) and its new calls are priced. Each new take is checked like every take and may earn the call's one automatic retake at our cost (a line not heard or said in another character's voice, or an opening off its planned framing); a moderation refusal is released and never retried. TWO CALLS, PRICE FIRST: sent WITHOUT confirmed it prices the render and reserves nothing (quotedOnly: true, the lines, credits); sent again with confirmed: true it reserves exactly the quoted lines and queues the takes. The flag is optional rather than a required true because a field that must be true to validate cannot separate a confirmed call from an unconfirmed one. A chapter whose stored compile is not ready yet is prepared in the background (its line voiced and its shots planned), which can take a few minutes: ${RENDER_QUOTE_PREPARING_UNIT_SENTENCE} Refused before the price: a text-only chapter, a chapter not in the deck, a call id the chapter does not have (or a call of a changed chapter), and a cast member with no body figure — with the action that fixes it in details.refusal (and details.blocked). Review or complete only. Returns a shareable per-chapter previewUrl. Requires Idempotency-Key. Scope: artifact:publish — a read-only key can neither spend nor ask what spending would cost.
