+### Path Parameters (Go 1.22+)
+
+Intake registers Go 1.22+ ServeMux patterns, so you can use `{name}` segments
+and retrieve them with `r.PathValue`.

+```go
+app.AddEndpoint(http.MethodGet, "/users/{id}", func(w http.ResponseWriter, r *http.Request) {
+    id := r.PathValue("id")
+    fmt.Println("user id:", id)
