# Focus Desk

A self-contained, vanilla task management web app. No dependencies, no build step.

## Running

```bash
cd /path/to/project
python3 -m http.server 8000
```

Then open http://localhost:8000 in a browser.

## Manual Verification Checklist

### Create
- Fill "Title" (required) and optionally Notes, Priority, Due Date, then click **Add Task**.
- Submit with a blank/whitespace title → inline error appears, task not added.
- Task appears at top of list with correct priority color border and badge.

### Edit
- Click the pencil icon on a task → modal opens pre-filled.
- Change any field, click **Save** → task updates.
- Clear the title, click Save → error shown, modal stays open.
- Press Escape or click backdrop or Cancel → modal closes without saving.

### Complete / Incomplete toggle
- Check the checkbox → task moves to "completed" style (strikethrough).
- Uncheck → reverts to active style.

### Delete
- Click the trash icon → task removed immediately.

### Search & Filters
- Type in the search box → filters titles AND notes case-insensitively.
- Change Status filter (All / Active / Completed) → list updates.
- Change Priority filter → list updates.
- Combine all three → only matching tasks shown.
- No matches → empty state message appears.

### Counts
- Header chips show correct Total / Active / Completed at all times.

### Persistence
- Add tasks, reload page → tasks still present.
- Manually corrupt `focus_desk_tasks` in localStorage to invalid JSON → app starts with empty list, no crash.

### Responsive layout
- At 390 px viewport: no horizontal overflow, form fields stack vertically, filters stack.
- At 1440 px viewport: centered layout, comfortable spacing.
