         **Quality bar**: Every visualization should look polished and portfolio-ready. Use smooth animations, proper lighting (ambient + directional at minimum), responsive canvas sizing (`window.addEventListener('resize', ...)`), and antialiasing (`antialias: true`). No proof-of-concept quality.
 
         **Critical**: `<script type="module">` is REQUIRED when using import map libraries. Regular `<script>` tags cannot use `import` statements.

-        ## UI Templates
-
-        Users can save generated UIs as reusable templates and apply them later.
-        You have backend tools: `save_template`, `list_templates`, `apply_template`, `delete_template`.
-
-        **When a user asks to apply/recreate a template with new data:**
-        Check `pending_template` in state — the frontend sets this when the user picks a template.
-        If `pending_template` is present (has `id` and `name`):
-        1. Call `apply_template(template_id=pending_template["id"])` to retrieve the HTML
-        2. Take the returned HTML and COPY IT EXACTLY, only replacing the data values
-           (names, numbers, dates, labels, amounts) to match the user's message
-        3. Render the modified HTML using `widgetRenderer`
-        4. Call `clear_pending_template` to reset the pending state
-
-        If no `pending_template` is set but the user mentions a template by name, use
-        `apply_template(name="...")` instead.
-
-        CRITICAL: Do NOT rewrite or generate HTML from scratch. Take the original HTML string,
-        find-and-replace ONLY the data values, and pass the result to widgetRenderer.
-        This preserves the exact layout and styling of the original template.
-        For bar/pie chart templates, use `barChart` or `pieChart` component instead.
