+[✓] Story 16.0: Frontend - Delete habit with confirmation
+    Commit: 46dc3a5
+    Date: 2026-02-10
+    
+    Implementation:
+    - Added delete button with trash icon (lucide trash-2) to each habit card
+    - Delete button styled with 32x32px size, border, hover state with red color
+    - Hover state changes border and background to danger color (rgba(239, 68, 68, 0.1))
+    - Created delete confirmation modal (id='deleteModal') with modal-overlay pattern
+    - Confirmation modal shows message: "Ștergi obișnuința {name}?" with habit name
+    - Modal includes Cancel button (btn-secondary) and Delete button (btn-danger)
+    - Delete button uses destructive red styling (.btn-danger class)
+    - Added showDeleteModal(habitId, habitName) function to display confirmation
+    - Added hideDeleteModal() function to close modal
+    - Added confirmDelete() async function to execute DELETE API call
+    - Delete button disabled during deletion with loading text "Se șterge..."
+    - On successful delete: hides modal, shows success toast, reloads habits list
+    - On error: shows error toast, re-enables delete button, keeps modal open
+    - Habit name properly escaped for XSS protection when passed to modal
+    - All styling uses CSS variables for theme consistency
+    
+    Tests:
+    - Created dashboard/test_habits_delete_ui.py with 10 comprehensive tests
+    - Tests for delete button CSS styling (size, border, hover, danger color) [AC1]
+    - Tests for trash-2 icon inclusion in habit cards [AC1]
+    - Tests for confirmation modal structure with Romanian message [AC2]
+    - Tests for Cancel and Delete buttons with correct handlers [AC3]
+    - Tests for btn-danger destructive red styling [AC4]
+    - Tests for DELETE API call to /api/habits/{id} endpoint [AC5]
+    - Tests for loadHabits() call after successful deletion (list refresh) [AC5]
+    - Tests for error handling with toast notification [AC6]
+    - Tests for modal show/hide functions and active class toggle
+    - Summary test verifying all 7 acceptance criteria [AC7]
+    - All 10 tests pass ✓
+    - All previous tests (schema, API endpoints, HTML, modal, display, check, form, styling, navigation, mobile) still pass ✓
+    
+    Files modified:
+    - dashboard/habits.html (added delete button, modal, CSS, and JavaScript functions)
+    - dashboard/test_habits_delete_ui.py (created)
