+# batida-landing
+
+Marketing/landing page for Batida. Static HTML served via Nginx.
+Separate git repository — self-contained.
+
+## Structure
+
+```
+index.html           → English landing page
+index.pt-br.html     → Portuguese landing page
+vs.html              → Comparison page (English)
+vs.pt-br.html        → Comparison page (Portuguese)
+Dockerfile           → Nginx static serving
+nginx.conf           → Nginx config (compression, caching)
+robots.txt           → SEO robots
+sitemap.xml          → SEO sitemap
+k8s/                 → Kubernetes deployment manifests
+```
+
+## Deployment
+
+Deployed to Kubernetes via `batida-infra`. The Dockerfile copies static HTML into an Nginx container. Manifests in `k8s/` define the deployment.
+
+## Key Facts
+
+- Fully static — no build step, no JavaScript framework
+- Two languages: English and Portuguese (separate HTML files)
+- Nginx handles gzip compression and static caching
+- SEO configured via robots.txt and sitemap.xml
+
+## Boundaries
+
+### Always
+- Keep both language versions in sync when updating content
+- Test HTML renders correctly in browser before committing
+
+### Never
+- Never add server-side logic or build tools — pure static HTML
+- Never commit secrets or environment-specific values
