Generate a self-contained, single-file HTML page in a minimal light design style to present information visually — workflows, guides, reports, comparisons, decision trees, reference docs, or other structured content. Use when the user asks to "create an HTML", "make a visual guide", "show this as a page", "present this as a polished light-themed page", or share structured information as a standalone webpage. Output has no external dependencies and opens directly in a browser.
