The `FilterPanel` component provides a standalone, reusable filter UI that can be placed next to any data view. It renders as a positioned dropdown anchored below a trigger button and supports single-select, multi-select, numeric range (with histogram), and fully custom filter editors declared as children.
+## Key Features
+
+- **Automatic Clear Buttons**: When a filter has active selections, a round clear button (×) appears in the filter header next to the count badge, making it easy to reset individual filters.
+- **Flexible Filter Types**: Supports string/option filters (single or multi-select), numeric range filters with histograms, and fully custom editors.
+- **Integrated State Management**: Use the `useFilterState` hook to manage all filter state in one place.

+## Clearing Filters
+
+Each filter group automatically displays a round clear button (×) in its header when it has active selections:
+
+- **String/option filters**: The clear button appears next to the selection count badge (e.g., "3 selected")
+- **Numeric range filters**: The clear button appears next to the "Range" indicator
+- **Custom filters**: The clear button appears when the filter has a value (non-null, non-undefined)
+
+The clear button includes a tooltip describing its action and can be clicked without expanding the filter. When clicked:
+
+- For string/option filters, all selections are cleared via `onFilterClear(filterKey)`
+- For range filters, the range is reset to `null` via `onRangeChange(filterKey, null)`
+- For custom filters, the value is set to `undefined` via `onCustomValueChange(filterKey, undefined)`
+
+Custom filter editors should not implement their own clear buttons; the header clear button handles this automatically.

Subject: [PATCH 4/6] Fix Storybook decorator HMR crash by using setAttribute
The applyThemeLink function was directly assigning to link.href property,
which triggered Vite's reactivity system and caused the browser to hang/crash.
Replace with setAttribute() to avoid HMR loops and ensure stable page loads.

Subject: [PATCH 6/6] Fix infinite render loop in FilterPanel stories
Resolved browser crash caused by infinite React render loops when
viewing FilterPanel stories in Storybook.
Root causes:
- Filter arrays defined inline in stories created new references on
every render
- useFilterState hook had filters array in useEffect dependency,
triggering on every reference change
- buildEditorMap() called on every render without memoization
Fixes applied:
- useFilterState: Added key serialization to detect actual filter
changes vs reference changes
- FilterPanel: Memoized editorMap with useMemo
- All stories: Wrapped filter definitions with useMemo for stable
references
All FilterPanel story variants now load and interact correctly without
crashing.
