Streaming MP3 player for ESP32-S3: HTTP chunked download → MP3 decode → resample → PCM out, fully PSRAM-resident, with abortable lifecycle. Audio output and HTTP transport are injected via abstract interfaces, so the component is project-agnostic.
An embedded HTTP server wrapping server lifecycle management, filesystem-backed static file serving, and handler registration into a small, thread-safe interface on top of the native ESP-IDF `esp_http_server` API. It is suitable for use in system services, provisioning flows, and device configuration UIs.
