Question: How to: 🏗 Architecture

Answer:
PowerKit uses a **contract-based architecture** with strict separation of concerns:

```text
┌─────────────────────────────────────────────────────────────────┐
│                         POWERKIT CORE                            │
│  Lifecycle • Cache • Options • Datastore • Theme Loader         │
└───────┬──────────────────────┬──────────────────┬───────────────┘
        │                      │                  │
        ▼                      ▼                  ▼

│ • Data       │─────▶│ • Colors        │◀──│ • Color     │
│ • State      │      │ • Icons         │   │   Palette   │
│ • Health     │      │ • Separators    │   │             │
│ • Context    │      │ • Formatting    │   │             │
└──────────────┘      └─────────────────┘   └─────────────┘
```


Question: How to: Key Principles

Answer:
1. **Plugins** provide data and semantics (state, health, context)
2. **Renderer** handles all UI decisions (colors, icons, formatting)
3. **Themes** define color palettes only
4. **Core** orchestrates the lifecycle and manages caching

This architecture ensures:

- ✅ Plugins never decide colors or formatting
- ✅ Themes are purely declarative
- ✅ Rendering is consistent across all plugins
- ✅ Easy to extend without breaking existing code

Question: How to: Element Order and Centered Layout

Answer:
PowerKit supports flexible element ordering with automatic centered layout:

```bash


Question: How to: 2-element orders (auto-expanded with windows):

Answer:
set -g @powerkit_status_order "session,plugins"  # Standard: session+windows LEFT, plugins RIGHT
set -g @powerkit_status_order "plugins,session"  # Inverted: plugins LEFT, windows+session RIGHT


Question: How to: 3-element orders enable CENTERED layout:

Answer:
set -g @powerkit_status_order "session,windows,plugins"  # session LEFT, windows CENTER, plugins RIGHT
set -g @powerkit_status_order "plugins,windows,session"  # plugins LEFT, windows CENTER, session RIGHT
set -g @powerkit_status_order "session,plugins,windows"  # session LEFT, plugins CENTER, windows RIGHT
```

Any element in the middle position will be automatically centered in the status bar.


Question: How to: Lazy Loading (SWR Caching)

Answer:
PowerKit uses Stale-While-Revalidate caching for optimal performance:

```bash


Question: How to: Example: TTL=300s, multiplier=3 → data up to 900s old can be returned while refreshing

Answer:
set -g @powerkit_stale_multiplier "3"
```

**How it works:**

- Fresh data (within TTL): Returns cached data immediately
- Stale data (within TTL × multiplier): Returns stale data immediately, refreshes in background
- Too old data (beyond TTL × multiplier): Blocks and refreshes synchronously

This ensures your status bar never hangs waiting for slow API calls or network requests.

Question: How to: 🔧 Creating Your Own Plugin

Answer:
PowerKit makes it easy to create custom plugins. Here's a minimal example:

```bash
#!/usr/bin/env bash
POWERKIT_ROOT="${POWERKIT_ROOT:-$(cd "$(dirname "${BASH_SOURCE[0]}")/../.." && pwd)}"
. "${POWERKIT_ROOT}/src/contract/plugin_contract.sh"

plugin_get_metadata() {
    metadata_set "id" "my_plugin"
    metadata_set "name" "My Plugin"
    metadata_set "description" "What this plugin does"
}

plugin_declare_options() {
    declare_option "icon" "icon" "󰀀" "Plugin icon"
    declare_option "cache_ttl" "number" "60" "Cache duration"
}

plugin_collect() {
    # Collect your data
    local value="42"
    plugin_data_set "value" "$value"
}

plugin_get_content_type() { printf 'dynamic'; }
plugin_get_presence() { printf 'always'; }
plugin_get_state() { printf 'active'; }
plugin_get_health() { printf 'ok'; }

plugin_render() {
    local value=$(plugin_data_get "value")
    printf '%s' "$value"
}

plugin_get_icon() {
    printf '%s' "$(get_option 'icon')"
}
```

Question: How to: 🎨 Creating Your Own Theme

Answer:
Themes are simple color definitions:

```bash
#!/usr/bin/env bash
declare -A THEME_COLORS=(
    # Status bar
    [statusbar-bg]="#1a1b26"
    [statusbar-fg]="#c0caf5"

    # Session
    [session-bg]="#7aa2f7"
    [session-fg]="#1a1b26"

    # Windows (variants auto-generated)
    [window-active-base]="#7aa2f7"
    [window-inactive-base]="#3b4261"

    # Health states (variants auto-generated)
    [ok-base]="#9ece6a"
    [info-base]="#7dcfff"
    [warning-base]="#e0af68"
    [error-base]="#f7768e"
)
```

The system automatically generates **6 color variants** (light/lighter/lightest/dark/darker/darkest) for each base color!
