// MARK: - BatteryChargeLimitSettingsView
//
// Custom configuration view shown in the plugin's settings page. Surfaces:
//   1. A larger limit slider with explanation of the "no auto-resume" semantics
//   2. SMC capability diagnostic (which inhibit path the helper found)
//   3. A note about how this differs from macOS Optimized Battery Charging
