-**Learning:** A logical, sequential heading structure (e.g., h1 -> h2 -> h3) in Markdown and HTML is critical for screen reader accessibility. Starting a document with a single H1 heading provides a clear entry point and allows users of assistive technology to easily understand the document's structure and navigate it effectively.

+**Learning:** A logical and sequential heading structure (e.g., `h1` -> `h2` -> `h3`) is not just for visual hierarchy, but is critical for screen reader users to navigate and understand the content of a page.

+**Action:** When working with Markdown or HTML, always ensure the heading levels are sequential and logically structured. Do not skip levels for stylistic reasons.
