-# Popup Update Panel Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Redesign the extension popup into a compact enterprise-style tool panel with clearer grouping, better spacing, and more readable update actions while keeping existing behavior unchanged.
-
-**Architecture:** Keep the popup behavior in `src/popup/index.ts` and focus most UI changes in `src/popup/view.ts`. Add only the minimum structural changes needed to support grouped cards, clearer update states, and button hierarchy, then verify the existing popup tests still cover the update workflow.
-
-**Tech Stack:** TypeScript, Chrome MV3 popup UI, Vitest, jsdom
-
---
-
-## File Map
-
- Modify: `src/popup/view.ts`
-  - Replace the current long text flow with grouped cards and clearer status blocks.
- Modify: `src/popup/index.html`
-  - Add popup-level CSS for layout, spacing, typography, and button hierarchy.
- Modify: `src/popup/index.ts`
-  - Keep logic unchanged unless the new view structure needs small status-render support changes.
- Modify: `tests/popup-entry.test.ts`
-  - Update popup rendering expectations for the redesigned layout.
-
-### Task 1: Lock the desired popup structure in tests
-
-**Files:**
- Modify: `tests/popup-entry.test.ts`
-
- [ ] **Step 1: Write the failing layout assertions**
-
-Update the logged-in and update-available popup tests to assert the new structure exists. Add checks for:
-
- a compact product header
- an account card/root section
- an update card/root section
- a primary update button and secondary guide button
-
-Use selectors that match the intended new DOM shape, for example:
-
-```ts
-expect(
-  dom.window.document.querySelector('[data-popup-account="card"]')
-).not.toBeNull();
-expect(
-  dom.window.document.querySelector('[data-popup-update="card"]')
-).not.toBeNull();
-```
-
- [ ] **Step 2: Run the focused popup test**
-
-Run:
-
-```bash
-npm test -- tests/popup-entry.test.ts
-```
-
-Expected: FAIL because the current popup view does not expose the new grouped structure.
-
-### Task 2: Redesign the logged-in popup shell
-
-**Files:**
- Modify: `src/popup/view.ts`
- Modify: `src/popup/index.html`
-
- [ ] **Step 1: Implement the grouped popup shell**
-
-Change the logged-in renderer so it produces:
-
- a compact header
- an account card
- an update card container
- a low-emphasis footer action area
-
-Keep the same text content, just reorganized.
-
- [ ] **Step 2: Add popup CSS**
-
-Add scoped CSS in `src/popup/index.html` for:
-
- wider popup body
- neutral background
- white cards
- consistent spacing
- smaller title scale
- primary / secondary / tertiary button styles
-
-Do not add animation-heavy or branding-heavy styles.
-
- [ ] **Step 3: Re-run popup tests**
-
-Run:
-
-```bash
-npm test -- tests/popup-entry.test.ts
-```
-
-Expected: PASS for structure-related checks, with any remaining failures isolated to update-state details.
-
-### Task 3: Redesign update-state rendering
-
-**Files:**
- Modify: `src/popup/view.ts`
- Modify: `src/popup/index.ts` (only if required)
-
- [ ] **Step 1: Write or update state-specific assertions**
-
-Ensure tests cover:
-
- `checking` state shows a compact progress line
- `latest` state hides download actions
- `available` state shows current version, latest version, notes, and action buttons
- `error` state renders a readable warning block
-
- [ ] **Step 2: Run the focused tests**
-
-Run:
-
-```bash
-npm test -- tests/popup-entry.test.ts
-```
-
-Expected: FAIL on any states not yet aligned to the new view.
-
- [ ] **Step 3: Implement state-specific card rendering**
-
-Refactor `renderUpdateStatus()` to keep one card shell and swap state bodies inside it. Make the available-update state visually prominent but restrained.
-
- [ ] **Step 4: Verify**
-
-Run:
-
-```bash
-npm test -- tests/popup-entry.test.ts tests/update-check.test.ts
-```
-
-Expected: PASS.
-
-### Task 4: Verify the popup still works end-to-end
-
-**Files:**
- Modify: `src/popup/view.ts` if polish is needed
- Modify: `src/popup/index.html` if polish is needed
-
- [ ] **Step 1: Build the release popup**
-
-Run:
-
-```bash
-npm run build:release
-```
-
-Expected: PASS and updated popup assets written to `dist/`.
-
- [ ] **Step 2: Run the full test suite**
-
-Run:
-
-```bash
-npm test
-```
-
-Expected: PASS.
-
- [ ] **Step 3: Manual smoke check**
-
-Open the unpacked extension popup from `dist/` and confirm:
-
- title no longer wraps into a giant stacked block
- account status is easy to scan
- update information reads clearly
- buttons are visually distinct and not cramped
-
- [ ] **Step 4: Commit**
-
-```bash
-git add src/popup/view.ts src/popup/index.html src/popup/index.ts tests/popup-entry.test.ts
-git commit -m "feat: redesign popup update panel"
-```

-# Popup Update Panel Design
-
-## Goal
-
-Redesign the extension popup so it feels like a compact internal tool instead of a stretched document. The new popup should prioritize readability, clear grouping, and obvious update actions while keeping the interaction model unchanged.
-
-## Confirmed Direction
-
- Visual style: enterprise tool
- Primary problem to solve: information feels crowded and hard to read
- Layout freedom: use whatever structure best improves clarity
-
-## Scope
-
-This change only redesigns the popup presentation layer:
-
- improve popup layout
- improve spacing and typography
- improve button hierarchy
- improve update-status presentation
-
-This change does not alter:
-
- auth flow
- update-check logic
- download behavior
- background message behavior
-
-## Layout
-
-Use a grouped card layout instead of one long text column.
-
-Recommended structure:
-
-1. Header
-   - compact product title on one line
-2. Account card
-   - login state
-   - current user name
-3. Update card
-   - current version
-   - latest version or current status
-   - release notes
-   - primary and secondary action buttons
-   - short follow-up instruction text
-4. Footer action
-   - low-emphasis sign-out button
-
-## Visual Rules
-
- Increase popup width to a more usable fixed tool width.
- Use a soft neutral page background with white content cards.
- Reduce title size significantly from the current oversized stacked text.
- Use a clear type scale:
-  - product title: medium emphasis
-  - section title: medium emphasis
-  - status/version rows: normal emphasis
-  - helper text: smaller and lighter
- Keep the palette restrained and neutral.
- Make `下载更新包` the primary button.
- Make `下载使用说明` a secondary button.
- Make `退出登录` a tertiary or low-emphasis button.
-
-## Update State Presentation
-
- `checking`: show a compact in-progress line inside the update card.
- `latest`: show a simple success-style status without action buttons.
- `available`: show a clear “发现新版本” status block with versions and actions.
- `error`: show a readable warning block instead of generic broken-looking text flow.
-
-## Content Rules
-
- Keep product name to one visual line or two short lines max.
- Avoid large paragraphs in the popup.
- Release notes should stay as a compact bullet list.
- The post-download instruction should be one concise sentence.
- Version labels should align consistently so the user can compare current/latest quickly.
-
-## Implementation Notes
-
- Keep the existing popup DOM entrypoints and rendering flow.
- Focus changes in `src/popup/view.ts` first.
- Only adjust popup controller code if needed to support cleaner status rendering.
- Prefer CSS embedded in the popup HTML/view flow only as needed; do not expand scope into unrelated refactors.
-
-## Testing
-
-Add or update popup rendering tests for:
-
- logged-in layout still renders correctly
- available update state still shows current/latest versions
- update action buttons still exist
- latest/error states still render expected text
-
-## Out of Scope
-
- new popup features
- star chart page banners
- animation-heavy UI
- branding-heavy marketing visuals
