    The Lavendly v1 API: build a video from shots, price it, generate the
    scenes, render the film, and publish it. Authenticate with a Bearer API key
    (lv_...) from Settings > API. Rate limits are per account per minute: 20
    writes, 60 render polls, 120 other reads; a 429 carries Retry-After and
    retry_after_ms. Errors are { error: { code, message } }; 5xx adds a ref. The
    same API is an MCP server at https://mcp.lavendly.ai/mcp and in the
    @lavendly/mcp npm package.
