+# Aether Events — Unified Launcher Configuration (Vision v3.1)
+
+> **Status:** Strategic Design / Unified Proposal
+> **Author:** Gemini CLI (Interactive Agent)
+> **Target:** Full consistency across all configuration modules.
+
+## 1. Unified Design Language
+
+To eliminate the "created by 3 different people" feel, all components must strictly adhere to this shared specification.
+
+### 1.1 Color Palette & Semantics
+- **Primary (Blue):** Main actions, active tabs, and standard configuration toggles.
+- **Secondary (Green):** Safe actions (Connect, Sync, Apply).
+- **Warning (Orange):** Technical overrides that require caution (Timers, Native Shell).
+- **Error (Red):** Destructive actions (Resets, Shutdown, Kill Apps).
+- **Surface (Gray):** Containers, input backgrounds, and inactive states.
+
+### 1.2 Typography & Spacing
+- **Section Headers:** `text-sm font-bold uppercase tracking-tight` (Provided by Wrapper).
+- **Field Labels:** `text-[10px] font-bold uppercase tracking-wider opacity-60 mb-1`.
+- **Sub-Descriptions:** `text-[9px] italic opacity-40 leading-snug mt-1`.
+- **Status Badges:** `text-[8px] font-bold uppercase tracking-tighter`.
+- **Grid Standard:** 
+    *   Single Column for complex fields.
+    *   `grid-cols-2` with `gap-4` for standard inputs.
+    *   `grid-cols-3` or `grid-cols-4` only for small buttons or icon toggles.
+

+
+## 2. Structural Reorganization (The "Aether" Layout)
+
+The menu is now a **Vertical Sidebar Modal**. This allows for persistent navigation while dedicating the large right pane to content.
+
+### Tab 1: 🖥️ Display (General Operator)
+*Focus: What the screen looks like.*
+- **Category: Layout & UI**
+    - Presets: Oral/Default vs Poster Kiosk (One-tap setup).
+    - Toggles: Header, Menu, Footer, Times visibility.
+    - Formatting: Clock (12/24h), Date formats.
+- **Category: Screen Saver**
+    - Idle Timeout (Minutes).
+    - Mode: Image Cycle vs Video vs Custom.
+
+### Tab 2: 🔌 Connectivity (Onsite Tech)
+*Focus: How it talks to the network.*
+- **Category: WebSocket Control**
+    - Connection Status & Signal Strength.

+
+### Tab 3: 🔄 Sync & Health (Onsite Tech)
+*Focus: Data integrity and performance.*

+    - Status: Active vs Paused.
+    - Action: Force Sync Location (recursive metadata fetch).
+    - Stats: Cached Files vs Total Files (Progress bar).
+- **Category: System Telemetry**
+    - CPU & RAM usage (Visual gauges).
+    - Heartbeat monitor (Last success timestamp).
+    - Device Identity: Hostname, IP list, Local paths.
+
+### Tab 4: 🛠️ Native Shell (Specialized / Mac)
+*Focus: OS-level capabilities.*
+- **Category: App Control**

+
+## 3. Implementation Plan: The "Cohesion" Refactor
+
+1.  **Standardize `Launcher_Cfg_Section.svelte`:** Ensure padding and spacing are baked into the wrapper so children don't have to define it.
+2.  **Create `Launcher_Cfg_Field.svelte`:** A new helper component to handle the Label + Description + Input pattern consistently.
+3.  **Audit Sub-Components:** Update all 10 components to use the new colors, grid patterns, and typography.
+4.  **Polish Transitions:** Ensure the Modal entry and Tab switching are butter-smooth with Svelte 5 transitions.
