+# CUSTOMIZATION-PLAN.md — White-Label / Multi-Instance Theming
+
+## Problem
+
+Regional mesh admins (e.g. CascadiaMesh) fork the analyzer and manually edit CSS/HTML to customize branding, colors, and content. This is fragile — every upstream update requires re-applying customizations.
+
+## Goal
+
+A `config.json`-driven customization system where admins configure branding, colors, labels, and home page content without touching source code. Accessible via a **Tools → Customization** UI that outputs the config.
+
+## Direct Feedback (CascadiaMesh Admin)
+
+Customizations they made manually:
+- **Branding**: Custom logo, favicon, site title ("CascadiaMesh Analyzer")
+- **Colors**: Node type colors (repeaters blue instead of red, companions red)
+- **UI styling**: Custom color scheme (deep navy theme — "Cascadia" theme)
+- **Home page**: Intro section emojis, steps, checklist content
+
+Requested config options:
+- Configurable branding assets (logo, favicon, site name)
+- Configurable UI colors/text labels
+- Configurable node type colors
+- Everything in the intro/home section should be configurable
+
+## Config Schema (proposed)
+
+```json
+{
+  "branding": {
+    "siteName": "CascadiaMesh Analyzer",
+    "logoUrl": "/assets/logo.png",
+    "faviconUrl": "/assets/favicon.ico",
+    "tagline": "Pacific Northwest Mesh Network Monitor"
+  },
+  "theme": {
+    "accent": "#20468b",
+    "accentHover": "#2d5bb0",
+    "navBg": "#111c36",
+    "navBg2": "#060a13",
+    "statusGreen": "#45644c",
+    "statusYellow": "#b08b2d",
+    "statusRed": "#b54a4a"
+  },
+  "nodeColors": {
+    "repeater": "#3b82f6",
+    "companion": "#ef4444",
+    "room": "#8b5cf6",
+    "sensor": "#10b981",
+    "observer": "#f59e0b"
+  },
+  "home": {
+    "heroTitle": "CascadiaMesh Network Monitor",
+    "heroSubtitle": "Real-time packet analysis for the Pacific Northwest mesh",
+    "steps": [
+      { "emoji": "📡", "title": "Connect", "description": "Link your node to the mesh" },
+      { "emoji": "🔍", "title": "Monitor", "description": "Watch packets flow in real-time" },
+      { "emoji": "📊", "title": "Analyze", "description": "Understand your network's health" }
+    ],
+    "checklist": [
+      { "question": "How do I add my node?", "answer": "..." },
+      { "question": "What regions are covered?", "answer": "..." }
+    ],
+    "footerLinks": [
+      { "label": "Discord", "url": "https://discord.gg/..." },
+      { "label": "GitHub", "url": "https://github.com/..." }
+    ]
+  },
+  "labels": {
+    "latestPackets": "Latest Packets",
+    "liveMap": "Live Map"
+  }
+}
+```
+
+## Implementation Plan
+
+### Phase 1: Config Loading + CSS Variables (Server)
+- Server reads `config.json` theme section
+- New endpoint: `GET /api/config/theme` returns merged theme config
+- Client injects CSS variables from theme config on page load
+- Node type colors configurable via `window.TYPE_COLORS` override
+
+### Phase 2: Branding
+- Config drives nav bar title, logo, favicon
+- `index.html` rendered server-side with branding placeholders OR
+- Client JS replaces branding elements on load from `/api/config/theme`
+
+### Phase 3: Home Page Content
+- Home page sections (hero, steps, checklist, footer) driven by config
+- Default content baked in; config overrides specific sections
+- Emoji + text for each step configurable
+
+### Phase 4: Tools → Customization UI
+- New page `#/customize` (admin only?)
+- Color pickers for theme variables
+- Live preview
+- Branding upload (logo, favicon)
+- Export as JSON config
+- Home page content editor (WYSIWYG-lite)
+
+### Phase 5: CSS Theme Presets
+- Built-in themes: Default (blue), Cascadia (navy), Forest (green), Midnight (dark)
+- One-click theme switching
+- Custom theme = override any variable
+
+## Architecture Notes
+
+- Theme CSS variables are already in `:root {}` — just need to override from config
+- Node type colors used in `roles.js` via `TYPE_COLORS` — make configurable
+- Home page content is in `home.js` — extract to template driven by config
+- Logo/favicon: serve from config-specified path, default to built-in
+- No build step — pure runtime configuration
+- Config changes take effect on page reload (no server restart needed for theme)
+
+## Priority
+
+1. Theme colors (CSS variables from config) — highest impact, lowest effort
+2. Branding (site name, logo) — visible, requested
+3. Node type colors — requested specifically
+4. Home page content — requested
+5. Customization UI — nice to have, lower priority
