スケルトン構造ビルダー for ライティング

I'm writing a piece with this central tension: [paste chosen angle from Prompt 1]. Build me a skeleton not an outline. A skeleton has the minimum structure needed to hold the piece upright. Every section exists because removing it would collapse something. For each section give me: what it does (not what it says), why it comes at this specific point in the sequence, and the one question it must answer before the next section can land. No bullet points of talking points. No topic sentences. Only the architecture.
