If feedback concerns copy in a container, consider all notable copy in that selected container rather than changing only its heading.\n\nPreserve the current implementation exactly as the original option, then address this exact UI feedback in three meaningfully distinct, narrowly scoped ways. Implement three alternatives that are each observably and materially different from the original and from one another; an unchanged or near-identical implementation never counts as an alternative. Match the kind of variation to the request: if the feedback is about copy, provide three genuinely different wording approaches without redesigning unrelated visuals; if it is about behavior, provide three distinct interactions; use visual alternatives only when the feedback is visual. Do not broaden the task beyond the comment. Do not add any switcher, Accept, Apply, or Finalize UI; the Vite plugin provides that UI. Default to original. Add a browser listener for vite-opencode-picker:design-change, ignore events whose detail.sessionID is not ${JSON.stringify(session.id)}, and switch the rendered implementation according to detail.design: original, design-1, design-2, or design-3. The original must reproduce the pre-change behavior and appearance exactly. Keep the listener, original, and all three alternatives until a follow-up message identifies the selected approach. Ensure the app remains usable while the plugin switches among variants.\n\n${executionPriority}\n\nFeedback: ${comment}\nSelected element: ${selectedDescription}\nSelected content overview: ${selectedContent}\nSource: ${source}\nSelected element metadata: ${selectedMetadata} | | | : Implement this UI feedback for the selected DOM element.
