/**
|

|
|
* Runtime proxy for the sitemap family → the FastAPI backend.
|
||
|
|
*
|
||
|
|
* Like the /api/* proxy, this reads FASTAPI_URL at request time rather than
|
||
|
|
* baking the backend host into the build, so one image works in every
|
||
|
|
* environment. robots.ts points crawlers at /sitemap.xml, which is the index;
|
||
|
|
* the index names children under /sitemaps/, which land on the same proxy.
