+ * platforms. The limitation below applies only to *streaming* chunked
+ * responses where data arrives slowly over a long period.
+ *
+ * Streaming chunked responses are NOT supported (all platforms):
+ *   The read helpers (http_read_loop_result, http_read_fully) block the main
+ *   event loop until all response data is received. For streaming responses
+ *   where data trickles in slowly (e.g., TTS streaming via ffmpeg proxy),
+ *   this starves the event loop on both ESP-IDF and Arduino. If data arrives
+ *   just often enough to avoid the caller's timeout, the loop runs
+ *   indefinitely. If data stops entirely, ESP-IDF fails with
+ *   -ESP_ERR_HTTP_EAGAIN (transport timeout) while Arduino spins with
+ *   delay(1) until the caller's timeout fires. Supporting streaming requires
+ *   a non-blocking incremental read pattern that yields back to the event
+ *   loop between chunks. Components that need streaming should use
+ *   esp_http_client directly on a separate FreeRTOS task with

+ *       transfers. When esp_http_client_read() returns 0 for a completed
+ *       chunked response, read() returns 0 and is_read_complete() returns
+ *       true, so callers get COMPLETE from http_read_loop_result().
+ *

+ *       Chunked responses are decoded internally (see

+ *       read() returns 0 to indicate "all content read" (not
+ *       HTTP_ERROR_CONNECTION_CLOSED).
+ *
