Act as an expert hardware engineer. Design a single-board ultra-compact wearable smartwatch/smartband PCB using a 4-layer stackup. The board must include the following blocks and components, and they must be connected using standard interfaces:

1. CORE: ESP32-S3 microcontroller module (suggest ESP32-S3-WROOM-1 or a compact variant with internal PSRAM for TinyML).
2. LORA: SX1262 LoRa transceiver tuned for 915MHz with all necessary matching circuitry and a compact 915MHz ceramic chip antenna. Connect to ESP32 via SPI.
3. HEALTH SENSOR: MAX30102 pulse oximeter and heart-rate sensor. Place it on the Bottom Layer of the PCB with an isolation slot for the LEDs. Connect via I2C.
4. TEMPERATURE SENSOR: TMP117 high-accuracy digital temperature sensor. Connect via I2C.
5. WIRELESS CHARGING & POWER: BQ51013B Qi-compliant wireless power receiver connected to a micro Lipoly battery charger (like MCP73831) to charge a 3.7V LiPo battery. Include a 3.3V LDO regulator (like AP2112K-3.3) to power the ESP32-S3 and sensors.
6. PROGRAMMING: Include small exposed pads (Pogo Pins layout) on the bottom or edge for GND, TX, RX, IO0, and EN to flash the code, avoiding bulky USB connectors.

Please generate the complete schematic wiring diagram, place the components to optimize for a tiny round or rectangular wearable form factor, and wire the connections. Ensure all decoupling capacitors (100nF and 10uF) are added to the VCC pins of every IC.
