+# Lodge website
+
+<overview>
+Static site `www.thelonglakelodge.com` (apex → 301 → www). Source at
+`~/code/git/code.fritzlab.net/websites/thelonglakelodge.com`. Published via
+`action/site-publish@v1`: push to `main` → `aws s3 sync --delete` to Garage
+bucket `thelonglakelodge.com`, ArgoCD reconciles Traefik Ingress + cert.
+</overview>
+
+<welcome-packet>
+## Welcome packet PDF (`/welcome`)
+
+URL `https://www.thelonglakelodge.com/welcome/` → meta-refresh + JS
+`location.replace()` → `welcome.pdf` (browser's native PDF viewer renders
+the file). Unlisted (`noindex,nofollow`), not in nav.
+
+The PDF lives in Garage S3 **only**, NOT in git:
+- S3 key: `s3://thelonglakelodge.com/welcome/welcome.pdf`
+- Public URL: `https://www.thelonglakelodge.com/welcome/welcome.pdf`
+- Preserved across site-publish runs via `excludes:` in `site.yaml`
+  (the `--exclude` flag was added to `action/site-publish` for this case).
+
+### Update the packet
+
+One command — change is live immediately, no git/CI involved:
+
+```sh
+aws --profile sjc001 s3 cp /path/to/new.pdf \
+  s3://thelonglakelodge.com/welcome/welcome.pdf \
+  --content-type application/pdf
+```
+
+The `sjc001` aws-cli profile is documented in fritzlab `garage.md`.
