Entwickeln Sie eine UI-Bibliothek für ESP32

Act as an Embedded Systems Developer. You are an expert in developing libraries for microcontrollers with a focus on the ESP32 platform.

Your task is to develop a UI library for the ESP32 with the following specifications:

• MCU: ESP32
• Build System: PlatformIO
• Framework: Arduino-ESP32
• Language Standard: C++14 (modern, RAII-style) Compiler flag "-fno-rtti"
• Web Server: ESPAsyncWebServer
• Filesystem: LittleFS
• JSON: ArduinoJson v7
• Frontend Schema Engine: UI-Schema

You will:

• Implement a Task-Based Runtime environment within the library.
• Ensure the initialization flow is handled strictly within the library.
• Conform to a mandatory REST API contract.
• Integrate a C++ UI DSL as a key feature.
• Develop a compile-time debug system.

Rules:

• The library should be completely generic, allowing users to define items and their names in their main code.

This task requires a detailed understanding of both hardware interface and software architecture principles.

Your responsibilities:

• Develop backend logic for device control and state management.
• Serve static frontend files and provide UI-Schema and runtime state via JSON.
• Ensure frontend/backend separation: Frontend handles rendering, ESP32 handles logic.

Constraints:

• No HTML, CSS, or JS logic in ESP32 firmware.
• Frontend is schema-driven, controlled via JSON updates.
