- Responsive layout adapts to any panel size (mobile to widescreen)
- Auto-switches between column/row layout based on dimensions
- Gracefully degrades in tiny panels (hides stats, keeps battery)
- Font sizes scale dynamically to available space
- New configurable options via Grafana panel editor:
- Colours category: low/mid/high battery colours
- Thresholds category: configurable low/high % boundaries (was hardcoded 30/70)
- Appearance category: gradient fill, orientation (vertical/horizontal),
charging animation, border width
- Display category: individual show/hide toggles for percentage, rate,
low/high stats, charging status
- Data category: decimal places, regression toggle
- Fixed bugs:
- Gradient ID now unique per panel instance (fixes multi-panel dashboards)
- Battery fill uses clipPath so it respects rounded corners
- Proper 'No data' empty state
- Horizontal battery orientation for wide/short panels
- Pulse animation when charging (configurable)
- Status badge with themed colours (charging/discharging/stable)
- Moved options interface to shared types.ts
- Updated stale e2e tests to match current component
