+[✓] Story 8.0: Frontend - Create habit form modal
+    Commit: 97af2ae
+    Date: 2026-02-10
+    
+    Implementation:
+    - Added modal HTML structure to habits.html with id='habitModal'
+    - Modal overlay uses dashboard styling patterns (overlay + modal container)
+    - Form includes text input for habit name (id='habitName', required)
+    - Form includes radio button group for frequency selection
+    - Two radio options: daily (default, checked) and weekly
+    - Custom styled radio buttons using .radio-group and .radio-label classes
+    - Radio buttons hidden, labels styled as clickable cards
+    - Selected radio shows accent background color
+    - Modal actions with Cancel (btn-secondary) and Create (btn-primary) buttons
+    - Cancel button calls hideHabitModal()
+    - Create button calls createHabit() and starts disabled
+    - Modal CSS follows dashboard patterns: modal-overlay, modal, modal-title, form-group, form-label, modal-actions
+    - Added toast notification element for user feedback
+    - JavaScript: showAddHabitModal() opens modal and resets form
+    - JavaScript: hideHabitModal() closes modal by removing 'active' class
+    - JavaScript: DOMContentLoaded event listener for form validation
+    - Input event listener on name field enables/disables Create button
+    - Create button disabled when name is empty (after trim)
+    - Enter key submits form if Create button is enabled
+    - createHabit() async function posts to /api/habits
+    - On success: hides modal, shows toast, calls loadHabits()
+    - On error: shows toast with error message
+    - showToast() function displays temporary notification (3 seconds)
+    - Modal uses CSS variables for theming (--bg-base, --border, --accent, etc.)
+    - Responsive design with max-width: 500px and 90% width
+    
+    Tests:
+    - Created dashboard/test_habits_modal.py
+    - Tests for modal structure (overlay, container, title)
+    - Tests for name input field with required indicator (*)
+    - Tests for frequency radio buttons (daily/weekly, daily checked by default)

+    - Tests for form validation logic (disable button, trim validation)
+    - Tests for modal show/hide logic (classList.add/remove 'active')
+    - Tests for API integration (fetch /api/habits POST)
+    - Tests for toast notification element and function
+    - Tests for event listeners (DOMContentLoaded, input, keypress)
+    - All 9 tests pass ✓
+    - All previous tests (schema, API endpoints, HTML structure) still pass ✓
+    
+    Files modified:
+    - dashboard/habits.html (added modal HTML, CSS, and JavaScript)
+    - dashboard/test_habits_modal.py (created)

+[✓] Story 10.0: Frontend - Check habit interaction
+    Commit: 775f171
+    Date: 2026-02-10
+    
+    Implementation:
+    - Added circular checkbox button to each habit card
+    - Checkbox positioned at start of card (before icon)
+    - Checkbox styled with border-radius: 50% for circular shape
+    - Checkbox shows check icon when checkedToday is true
+    - Checkbox has 'checked' and 'disabled' classes when already done today
+    - Clicking checkbox calls checkHabit(habitId, element) function
+    - checkHabit performs optimistic UI update (checks immediately)
+    - API call to POST /api/habits/{id}/check executed after UI update
+    - On success: streak element updated with response data, shows toast
+    - On error: checkbox reverts to unchecked state, shows error toast
+    - Checkbox is non-clickable (disabled) when already checked today
+    - Streak updates dynamically using id="streak-{habitId}" element
+    - Check icon reinitialized with lucide.createIcons() after adding
+    - Hover state for unchecked checkboxes (border-color change)

+    - Tests for check icon display and lucide reinitialization
+    - All 10 tests pass ✓

+    
+    Files modified:
+    - dashboard/habits.html (added checkbox CSS and checkHabit function)
