+# SPEC: Replace Prompt Dialog with Inline Comment Textarea
+
+## Overview
+
+The review approval flow uses `prompt()` for comments, which is a jarring browser popup. Replace it with a textarea in the detail modal. After submission, close the modal and return to the board.
+
+## Changes
+
+### dashboard.js
+- Add comment `<textarea>` in the detail panel review section
+- `submitReview()` reads from textarea instead of `prompt()`
+- On success, close the modal (`closeDetail()`) instead of re-rendering it
+
+### index.html
+- No structural changes needed (textarea is rendered by JS in the detail panel)
+
+### styles.css
+- Add styles for the comment textarea
+
+## Acceptance Criteria
+- [ ] Review section shows a textarea for optional comment
+- [ ] Clicking Approve/Request Changes submits with textarea content
+- [ ] Modal closes after successful submission
+- [ ] No browser `prompt()` popup
+
+## Notes
+- Textarea is always visible in the review section
+- Comment is optional (can be empty)
