Generate beautiful, self-contained HTML pages that visually explain systems, code changes, plans, and data. Use when the user asks for a diagram, architecture overview, diff review, plan review, project recap, comparison table, a visual explainer, or any visual explanation of technical concepts — including phrasings like "visualize this", "visualize a plan", "make it visual", "show me this visually", or "explain this visually". Also use proactively when you are about to render a complex ASCII table (4+ rows or 3+ columns) — present it as a styled HTML page instead.
