+Divan (دیوان)
+Copyright (C) 2026 Anas Rashid and Divan contributors
+
+This program is free software under the GNU General Public License version 3 (see LICENSE), with the
+additional terms below, which the GPL allows in its section 7. They apply to the code written for Divan by its
+authors. (The earlier .NET code at the tag dotnet-final is a fork of GanjoorService and stays under that
+project's licence; these terms do not apply to it.)
+
+Additional terms under section 7 of the GNU GPL version 3
+
+1. Attribution (section 7(b)). If you convey this work or a work based on it, keep this attribution in the
+ Appropriate Legal Notices it displays (for a website: its about page or footer):
+ "Based on Divan (https://git.anasrashid.net/anas/divan) by Anas Rashid, under the GNU GPL v3."
+
+2. Origin (section 7(c)). A modified version must be marked as different from the original, and must not
+ be presented as Divan, or as made, approved or endorsed by Divan or its authors.
+
+3. Names and logos (section 7(e)). This licence grants no rights under trademark law to the names, logos
+ and other brand features of Divan, listed in TRADEMARKS.md: among them the name دیوان / Divan for this
+ project and site, the shamsa and ترنج logos and icons, the tagline "ایک پاکستانی کی طرف سے، پاکستان کے
+ لیے", and the masthead and share-card designs. A modified version made available to the public must use
+ its own name and logo (see "Making your own site" in TRADEMARKS.md).
+
+The texts shown on the site are in the public domain; the Divan data is CC BY-SA 4.0 (see the divan-data
+repository). These terms concern only the software and Divan's brand.

+# Divan's name and logos
+
+The code is free software (GNU GPL v3, with the additional terms in [NOTICE](NOTICE)), and you are welcome to
+study it, change it and run your own site with it. Divan's **name and logos are not part of that licence**:
+they identify this project and its site, so that readers know what is Divan and what is not.
+
+## What belongs to Divan
+
+- The name **دیوان / Divan** used for this project, its site and its apps.
+- The logos and icons: the shamsa (illuminated medallion) and the ترنج (lobed medallion), in every form:
+ `web/public/logo/`, `web/public/favicon.*`, `web/public/icon-*.png`, `web/public/apple-touch-icon.png`,
+ `web/public/og-image.png`, and the logo drawn in the header and home page.
+- The tagline **ایک پاکستانی کی طرف سے، پاکستان کے لیے** with Pakistan's flag in the footer.
+- The masthead (the logo beside **اردو کا کلاسیکی ادب** between the couplet lines) and the share-card design.
+
+## What you may do
+
+- Say that your work is **based on Divan**, link to it, and describe what Divan is.
+- Run Divan unchanged for yourself or for testing, privately.
+- Use the name when writing about the project (articles, reviews, talks).
+
+## What you may not do
+
+- Run a public site, app or service from a modified copy under the Divan name or with its logos.
+- Use a name, domain, logo or design that could make people think your site is Divan or is endorsed by it.
+- Remove the attribution required by [NOTICE](NOTICE).
+
+## Making your own site
+
+1. Set your name and taglines in `web/src/lib/brand.ts`.
+2. Replace the logo files listed above with your own, and the logo in the header (`web/src/layouts/Base.astro`)
+ and home page (`web/src/pages/index.astro`).
+3. Rewrite the about page (`web/src/pages/about.astro`) for your project, keeping the attribution
+ "Based on Divan by Anas Rashid" from [NOTICE](NOTICE).
+4. Update `web/public/site.webmanifest`.
+
+Questions or permission requests: open an issue on the Divan repository.
