Put the chapters in a new order.

Puts the deck's chapters in a new order: order names every chapter's chapterIndex once, in the order they will play, or move puts one chapter just after another (afterChapterIndex) or first (afterChapterIndex: null). Free: nothing renders and every chapter keeps its takes; a rendered deck's video is stitched again in the new order. Chapters filmed in one render (a scene group: a chapter whose renderedWith names another, and that chapter) move as one block, side by side in their order; an order that pulls them apart is refused (pitch_deck_scene_group_split) and a move of one of them moves the whole group. The chapters are renumbered from 0 in their new order (each answer chapter's previousChapterIndex is its key before). How a chapter hands into the next and the black after it travel with it (a black whose chapter now ends the deck is taken out and named in droppedInterludes); music and sound laid on one chapter move with it, and a score composed to the old order keeps playing but no longer lands on the chapters (score: no_longer_fits) until it is scored again, priced. A draft plan, review or complete; on a draft the changed plan is queued for plan coverage again (planCoverage). A rendered deck waits while its video is being put together or its automatic fixes are running (409 pitch_deck_reorder_assembly_running, pitch_deck_reorder_auto_fix_running). A scene group pulled apart is refused with 409 pitch_deck_state_invalid (details.refusal.code: pitch_deck_scene_group_split), as is a rendered deck whose video is being put together (pitch_deck_reorder_assembly_running) or whose automatic fixes are reviewing or fixing it (pitch_deck_reorder_auto_fix_running); nothing changes. An order that does not name every chapter once is a 400. NOT metered and NOT confirmed. Requires Idempotency-Key. Scope: story:write.
