 Replace the style opening tag with `cssAuthoring.styleTag` when the tool returns a different one. **Each variant div contains exactly one top-level element**, same tag as the original; loose siblings break outline tracking and accept. First variant visible, all others `display: none`. The browser's MutationObserver accepts atomic or progressive arrival; accepting an arrived variant fences the worker, so later publications are rejected.

 Replace the style opening tag with `cssAuthoring.styleTag` when the tool returns a different one. **Each variant div contains exactly one top-level element**, same tag as the original; loose siblings break outline tracking and accept. First variant visible, all others `display: none`. The browser's MutationObserver accepts atomic or progressive arrival; accepting an arrived variant fences the worker, so later publications are rejected.

 Replace the style opening tag with `cssAuthoring.styleTag` when the tool returns a different one. **Each variant div contains exactly one top-level element**, same tag as the original; loose siblings break outline tracking and accept. First variant visible, all others `display: none`. The browser's MutationObserver accepts atomic or progressive arrival; accepting an arrived variant fences the worker, so later publications are rejected.

 description: Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary.

 Replace the style opening tag with `cssAuthoring.styleTag` when the tool returns a different one. **Each variant div contains exactly one top-level element**, same tag as the original; loose siblings break outline tracking and accept. First variant visible, all others `display: none`. The browser's MutationObserver accepts atomic or progressive arrival; accepting an arrived variant fences the worker, so later publications are rejected.
