+Organization profile, shared visual assets and repository configuration for
+[OpenArkStudio](https://github.com/OpenArkStudio).
+
+## Organization profile
+
+- [English profile](profile/README.md): displayed on the public organization page.
+- [中文介绍](profile/README_CN.md): Chinese version of the organization profile.
+
+## Visual identity
+
+OpenArkStudio, ark and arknet share a cradle hull and Inter 600 lettering in electric blue and cyan. The organization carries one dot, ark carries three modules, and arknet carries linked nodes. The selected horizontal lockup gives the symbol slightly more emphasis; all lettering uses vector outlines.
+
+All brand SVG masters are archived in this repository's [`assets/`](assets/) directory. Project READMEs reference these files; documentation sites retain matching local copies.
+
+| Asset | Use |
+| :--- | :--- |
+| [Organization icon](assets/openarkstudio-icon.svg) | Organization avatar and compact placements |

+| [Dark overview](assets/identity-overview-dark.png) | Dark backgrounds |
+| [Brand guide](assets/README.md) | File names, colors and usage |
+
+Preserve the original proportions and choose the `light`, `dark` or `mono` version for the background. See [Inter-OFL.txt](assets/Inter-OFL.txt) for the font license.
+
+## Shared configuration
 
 - ARK and arknet summarize GitHub Actions results in Discord after each workflow completes.
 - The Webhook is stored in the organization Actions secret `DISCORD_WEBHOOK_URL`.

+
+The selected identity combines the cradle symbol with Inter 600 lettering and electric blue / cyan. OpenArkStudio uses one dot, ark uses three modules, and arknet uses linked nodes.
+
+The horizontal lockup uses the selected **symbol emphasis** proportions: hull height 88, lowercase x-height 80, and a visible gap of 40 units. The organization symbol has a 17.6-unit optical lift beside the two-line OpenArk / STUDIO lettering.
+
+![Selected identity](identity-overview.png)
+
+## Files
+
+Replace `{brand}` with `openarkstudio`, `ark` or `arknet`.
+
+| File | Use |
+| --- | --- |
+| `{brand}-logo-light.svg` | Symbol and lettering on light backgrounds |
+| `{brand}-logo-dark.svg` | Symbol and lettering on dark backgrounds |

+
+All 27 identity SVGs have transparent backgrounds, accessible titles and outlined lettering. The three sharing-card SVGs use a light background and outlined captions. None require installed fonts or external font requests.
+
+## Colors and placement
+
+- Light backgrounds: blue `#1464F4`, cyan `#06BBDD`, text `#11213B`.
+- Dark backgrounds: blue `#508AFF`, cyan `#2CD6EE`, text `#F2F7FF`; preview background `#101D34`.
+- Preserve the SVG aspect ratio. In READMEs, set the width and allow the height to follow automatically.
+- Reference these masters from project READMEs. Local documentation-site copies must match the archived files.
