Shape a Real Article Outline

Write the heading structure of a short article — not six empty heading tags, but a real outline: one h1 for the article title, two h2 section headings, and one h3 sub-heading under the first section. Add one short paragraph under each heading so the structure has content. Rules: - Exactly one h1. - At least two h2 elements. - At least one h3 after the first h2. - Every heading is followed by a paragraph.
