/**
 * Create a Teddy & Pinguin bedtime story from an idea and wait for the finished prose.
 * Call this when someone asks for a story. If you already have a `runId` from a `pending`
 * result, call `get-story-result` instead of this export.
 *
 * @param input - `storyIdea` (1–500 chars) plus optional `contentLocale` (default `"de"`),
 *   `targetReadMinutes` (default 8, clamped to 5–12), and `maxWaitSeconds` (default 300,
 *   capped at 360). `0` performs one status read. Optional `series: { start: true }`
 *   starts a Story Series. `series: { continue: seriesId }` or `continueFromStoryId`
 *   writes the next episode.
 * @returns `ready` with the story, `pending` with a `runId` to resume, or `declined`,
 *   `unavailable`, `disconnected`, `invalid_input`
 *
 * @example
 * import generateStory from 'kody:@jpfi/stories/generate-story'
 *
 * const result = await generateStory({
 *   storyIdea: 'Teddy und Pinguin finden eine Sternenkarte im Schnee',
 *   targetReadMinutes: 10,
 * })
 * if (result.status === 'ready') console.log(result.story.prose)
