+ * - closeOnOverlay: Whether to close when clicking the overlay (default: true)
+ * - closeOnSwipeDown: Whether to close when swiping down on handle (default: true)
+ *
+ * Events:
+ * - update:modelValue: Emitted when visibility changes (for v-model support)
+ *
+ * Slots:
+ * - default: Content to display inside the bottom sheet
+ *
+ * Features:
+ * - Smooth slide-up animation
+ * - Drag handle at top for visual affordance
+ * - Close on tap outside (overlay)
+ * - Swipe down to close (touch gesture)
+ * - Teleported to body to avoid z-index issues

+ * Usage:
+ * <BottomSheet v-model="isFilterOpen">
