Use when planning a posting schedule, building a multi-platform content calendar, or reshaping one source asset into channel-native posts across X, LinkedIn, Instagram, Threads, Bluesky, TikTok, Facebook or YouTube — cadence, best-time slots, per-platform format limits, API publish caps, and a dated CSV or JSON calendar a scheduler can import. NOT the brand voice the posts speak in (that is `brand-voice`), NOT the editorial strategy of what to make (that is `content-engine`).
