### Library Count Label States
The library tab's count label switches between three visual states depending on what `refresh()` finds. The state is exposed as a Qt dynamic property `libraryCountState` so themes target it via attribute selectors:
```css
QLabel[libraryCountState="empty"] {
color: #a6adc8; /* dim text — search miss or empty folder */
}
QLabel[libraryCountState="error"] {
color: #f38ba8; /* danger color — directory unreachable */
font-weight: bold;
}
```
The `normal` state (`N files`) inherits the panel's default text color — no rule needed.
