+# KoTalk Brand Guide
+
+## Overview
+
+This package turns the approved raster logo concept into a reusable production asset set for KoTalk.
+
+- Reference intent: warm, calm, modern messenger mark
+- Primary use: app icon, favicon, PWA icon, Windows icon, docs, release pages
+- Master source: `branding/kotalk-logo-master.svg`
+
+## File Inventory
+
+### Master vectors
+
+- `branding/kotalk-logo-master.svg`
+- `branding/kotalk-logo-master.pdf`
+- `branding/kotalk-logo-master.eps`
+
+### PNG exports
+
+- Transparent: `branding/png/kotalk-transparent-{1024|512|256|192|180|128|64|32|16}.png`
+- White background: `branding/png/kotalk-white-1024.png`
+- Mono black: `branding/png/kotalk-mono-black-1024.png`
+- Mono white: `branding/png/kotalk-mono-white-1024.png`
+- Inverse for dark surfaces: `branding/png/kotalk-inverse-1024.png`
+
+### ICO exports
+
+- Windows app icon: `branding/ico/kotalk.ico`
+- Favicon bundle: `branding/ico/favicon.ico`
+
+### Applied runtime assets
+
+- Web app icons: `src/PhysOn.Web/public/`
+- Desktop app icons: `src/PhysOn.Desktop/Assets/`
+
+## Color System
+
+### Core colors
+
+- Ink: `#394350`
+- Warm accent: `#F05B2B`
+- Separator white: `#FFFFFF`
+
+### Supporting backgrounds
+
+- Paper: `#F7F3EE`
+- Night: `#141922`
+
+### Recommended backgrounds
+
+- White: `#FFFFFF`
+- Warm paper: `#F7F3EE`
+- Dark surface: `#141922`
+
+## Safe Area
+
+- Artboard: `1024 x 1024`
+- Recommended clear area from the artboard edge: `128px`
+- Do not scale the visible mark so large that any speech bubble or the center chevron approaches the outer 12% of the square
+
+## Minimum Use Size
+
+- Preferred minimum digital size: `24px`
+- Favicon minimum: `16px`
+- When rendering below `24px`, use the packaged ICO or PNG exports instead of re-rasterizing from screenshots
+
+## Usage Rules
+
+- Keep the mark square, centered, and unrotated
+- Use the transparent master for docs and UI surfaces when the background is already controlled
+- Use the white background exports for launcher and touch icons
+- Use the mono variants only where a single-color system is required
+
+## Do Not
+
+- Stretch or rotate the mark
+- Add shadows, glow, gradients, glass, or texture
+- Change the orange or dark brand colors arbitrarily
+- Add pattern backgrounds behind the mark
+- Recreate the logo from screenshots when the packaged vectors are available
+
+## Regeneration
+
+Run:
+
+```bash
+python scripts/branding/generate_kotalk_brand_assets.py
+```
+
+This regenerates the committed vector, PNG, ICO, and app-facing icon assets from the scripted master geometry.
