📝 Walkthrough

Summary by CodeRabbit

• UI Improvements
  • Clarified battery and AC power setting labels and descriptions.
  • Specified when integrated mode and Cardwire mode are enabled.

Walkthrough

The daemon settings UI updates power-related labels and descriptions. The battery option describes switching to integrated mode. The following option describes switching Cardwire mode on AC power. Controls and message wiring remain unchanged.

Changes

Daemon settings UI

Layer / File(s)	Summary
Power setting labels and descriptions crates/cardwire-gui/src/ui.rs	The battery description specifies automatic switching to integrated mode. The power setting uses “Switch mode on AC power” and describes AC-power mode switching.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 345ec

The AC-power setting label remains ambiguous and could confuse users about when automatic mode switching occurs. The risk is localized to UI clarity, so the PR is mergeable with explicit owner awareness or a follow-up label improvement.
