Creates a text-only engineering implementation plan as a single self-contained HTML page saved to specs/<name>.html — the plan authored directly in styled HTML plus a freeform HTML zone where the agent can author any custom HTML/CSS/SVG/JS (inline SVG diagrams, interactive toggles, comparison matrices, decision trees) that aids comprehension. No images are generated; visual richness comes from inline HTML/SVG only. Use when the user says "htmlspec", wants a text-only HTML implementation plan, a browser-openable spec, or a richly-formatted HTML engineering plan without per-section image generation.
