"""SSR frontend service: server-rendered content pages only (content.py). All
climate data comes from the backend's content API over HTTP (api_client.py) --
this process holds no data of its own and does no polars/DB work.

No static-asset mount here (repo-split Stage 4): every real topology routes
JS/CSS/images to backend's own StaticFiles mount -- prod/beta's Caddy never
sends those paths here, and backend's own dev/bare-metal reverse-proxy fallback
(THERMOGRAPH_FRONTEND_BASE_INTERNAL) only forwards the specific content paths
content.register() claims. A static mount here would just be unreachable dead
code in every deployment.
