+KEY FEATURES
+================================================================================
+
+1. Position-Based Ordering
+   - Tasks have explicit position field (0-indexed)
+   - Drag any task to any position instantly
+   - All affected tasks automatically renumbered
+   - Atomic operation — no race conditions
+
+2. Status-Based Filtering
+   - Projects: active, archived, paused
+   - Tasks: backlog, in_progress, done, blocked
+
+3. Smart Pagination
+   - Limit: 1-100 (projects), 1-500 (tasks)
+   - Offset for pagination
+   - Total count in response
+
+4. Project Statistics
+   - task_count: Total tasks
+   - completed_count: Done tasks
+   - overdue_count: Past due, not done
+
+5. Sorting Options
+   - position (default)
+   - due_date
+   - created_at
+   - -updated_at (descending)
+
