+# Cooldown Quick Action Buttons — Design Spec
+
+## Overview
+
+When a cooldown (drug, medical, booster) reaches 0 ("Ready"), the cooldown cell transforms into a clickable button that opens the corresponding Items subsection on Torn's website. For the booster cooldown, the user can configure in Settings whether the link targets boosters or alcohol.
+
+## UI Changes
+
+### Cooldown Cells (`LiveCooldownItem` / `CooldownItem`)
+
+When `remaining == 0` and an `actionURL` is provided:
+
+- **Background**: `Color.green.opacity(0.12)` fill
+- **Border**: `Color.green.opacity(0.25)`, `cornerRadius(6)`
+- **Action label**: Below "Ready" text, a subtle hint in `.caption2` font at `opacity(0.7)`:
+  - Drug: "Use Drug →"
+  - Medical: "Use Medical →"
+  - Booster: "Use Booster →" or "Use Alcohol →" (depending on setting)
+- **Behavior**: Entire cell is a `Button` that calls `BrowserManager.shared.open(url)`
+
+When cooldown > 0 or no `actionURL`: no visual or behavioral change from current implementation.
+
+### Target URLs
+
+| Cooldown | URL |
+|----------|-----|
+| Drug | `https://www.torn.com/item.php#drugs-items` |
+| Medical | `https://www.torn.com/item.php#medical-items` |
+| Booster (boosters) | `https://www.torn.com/item.php#boosters-items` |
+| Booster (alcohol) | `https://www.torn.com/item.php#alcohol-items` |
+
+### Settings
+
+New option in `SettingsView`: **"Booster cooldown link"**
+
+- `Picker` with two choices: "Boosters" (default), "Alcohol"
+- Stored in `@AppStorage("boosterCooldownTarget")` as `String` — value `"boosters"` or `"alcohol"`
+- Placed after the existing Reduce Transparency toggle in the settings layout
+
+## Data Flow
+
+- `LiveCooldownItem` and `CooldownItem` gain a new optional parameter: `actionURL: URL?`
+- `cooldownsSection` in `StatusView` constructs the URLs:
+  - Drug and Medical: static URLs
+  - Booster: reads `@AppStorage("boosterCooldownTarget")` to determine which URL to use
+- URL opening is delegated to `BrowserManager.shared.open()` (respects preferred browser setting)
+
+## Scope — What Does NOT Change
+
+- Cooldown notifications in `AppState` — unchanged
+- `AppState` logic — no modifications (feature is view-layer only)
+- Quick Links section — unchanged
+- Cooldown behavior when timer > 0 — unchanged
+- `CooldownItem` fallback (no `fetchTime`) renders action button using same logic based on `seconds == 0`
+
+## Visual Reference
+
+Style C from brainstorming: entire cooldown cell becomes a clickable button with green background, border, and subtle action text when ready.
