A lightweight, owl-themed application launcher for Wayland, built with GTK4 and Layer Shell.

## Features

- **Provider-based architecture** - Search applications, PATH commands, and systemd user services
- **Fuzzy search** - Fast, typo-tolerant matching across all providers
- **Filter tabs & prefixes** - Scope searches with UI tabs or `:app`, `:cmd`, `:uuctl` prefixes
- **Systemd integration** - Manage user services with submenu actions (start/stop/restart/status/journal)
- **GTK4 theming** - Respects system theme by default, with optional custom themes
- **CSS variables** - Full customization via config or custom stylesheets
- **Wayland native** - Uses Layer Shell for proper overlay behavior

## Theming

### GTK Theme (Default)

By default, Owlry inherits colors from your system GTK4 theme (Adwaita, Breeze, etc.).

### Owl Theme

Enable the built-in owl-inspired dark theme:

```toml
[appearance]
theme = "owl"
```

### Custom Theme

Create a custom theme file at `~/.config/owlry/themes/mytheme.css`:

```css
:root {
    --owlry-bg: #1e1e2e;
    --owlry-bg-secondary: #313244;
    --owlry-border: #45475a;
    --owlry-text: #cdd6f4;
    --owlry-text-secondary: #a6adc8;
    --owlry-accent: #f38ba8;
    --owlry-accent-bright: #f5c2e7;
}
```

Then reference it in config:

```toml
[appearance]
theme = "mytheme"
```
