+# SQLStack
+
+The SQLStack website: Rust-backed SQL and Python tools for data engineers.
+
+## Local preview
+
+Serve this directory with any static web server. For example:
+
+```sh
+python3 -m http.server 4173
+```
+
+Open `http://localhost:4173`. No build step or package installation is required to serve the site.
+
+The page uses self-hosted Inter and Space Grotesk fonts. Their licenses are included in
+`assets/fonts/`. Product icons are optimized PNG derivatives of the original brand artwork.
+
+The theme defaults to the system preference. The accessible header toggle saves an explicit
+light/dark preference in the browser. Without JavaScript, the page remains usable in light mode.
+
+## Checks
+
+Browser tests cover theme selection and persistence, keyboard navigation, responsive layouts,
+product statuses, sharing metadata and image dimensions. They require Node.js and Python 3:
+
+```sh
+npm ci
+npx playwright install chromium
+npm test
+```
+
+`CHROMIUM_EXECUTABLE_PATH` can point to an existing Chromium installation instead of downloading one.
+The test server starts and stops automatically. GitHub Actions runs the same checks without any
+publishing or deployment step.
+
+## Sharing assets
+
+`favicon.ico` contains 16px, 32px and 48px icons. PNG favicons and a 180px Apple touch icon use the
+original SQLStack mark on white backing for legibility in light and dark browser chrome.
+`assets/og-sqlstack.png` is an opaque 1200 × 630 sharing card using the original SQLStack wordmark
+and the site's Inter typography. These are raster derivatives, not replacement logos or SVG originals.
+
+Canonical and Open Graph/Twitter URLs target `https://sqlstack.io/`. Local previews can verify the
+metadata and assets, but public social-crawler validation requires a separately authorized deployment.
