# Mount static files (Next.js exported assets)
# We mount this AFTER the API routes defined in `ylff.server` so that API routes take precedence.
# However, FastAPI mounts match by path. "/" matches everything.
# So we need to be careful.
# But `StaticFiles` only handles requests if the file exists? No, it catches everything under mount path.
# So requests to /api/... might get caught if we mount at "/"?
# NO: FastAPI router matches first.
# Wait. `app = create_app()` includes routers.
# If we add mount("/") now, it acts as a catch-all?
# Actually, explicitly defined routes (like /api/v1/...) are checked before mounts?
# It depends on order... but `app.mount()` typically adds to the routes list.
# Since `app` is already created with API routes, appending mount("/") usually works as fallback.

# FastAPI docs say: "The order matters. Routes are matched in order."
# Since API routes were added in `create_app` (imported above), they are already in `app.router.routes`.
# `app.mount` adds to the end. So it effectively acts as fallback.
