+ * Mutates the provided URL by adding a cache-busting search parameter for CDNs that don't
+ * support custom headers. This helps avoid caching conflicts by making each request unique.
+ *
+ * Rather than relying on the Vary header which some CDNs ignore, we append a search param
+ * to create a unique URL that forces a fresh request.
+ *
+ * Example:
+ * URL before: https://example.com/path?query=1
+ * URL after: https://example.com/path?query=1&_rsc=abc123
+ *
+ * Note: This function mutates the input URL directly and does not return anything.
+ *
+ * TODO: Since we need to use a search param anyway, we could simplify by removing the custom
+ * headers approach entirely and just use search params.
