+ * ESP32S3-Viking - Board interface implementation for Bruce firmware
+ *
+ * Hardware:
+ *   - ESP32-S3-WROOM-1 N16R8 (16MB Flash, 8MB OPI PSRAM)
+ *   - ESP32-S3 GPIO Extension Board KIT B
+ *   - ILI9341 2.8" SPI TFT 240x320 (TENSTAR ROBOT)
+ *   - XPT2046 Resistive Touchscreen (TOUCH_CS=IO18, T_IRQ=IO8)
+ *     handled by TFT_eSPI built-in touch support (USE_TFT_eSPI_TOUCH)
+ *   - PN532 NFC/RFID (SPI - osobna magistrala, GPIO 9-14)
+ *   - WS2812 RGB LED (GPIO48)
+ *   - BOOT button (GPIO0)
+ *
+ * Wiring TFT (left side of KIT B, top to bottom, no cable crossing):
+ *   GND -> GND, 3V3 -> VCC
+ *   IO4 -> T_IRQ, IO5 -> T_DO/LCD_MISO, IO6 -> T_DIN/LCD_MOSI
+ *   IO7 -> T_CS, IO15 -> T_CLK/LCD_SCK
+ *   IO16 -> LCD_BL, IO17 -> LCD_DC
+ *   IO18 -> LCD_RST, IO8 -> LCD_CS *
+ * Wiring PN532 SPI (left side of KIT B, lower block):
+ *   IO9  -> PN532 SCK
+ *   IO10 -> PN532 MISO
+ *   IO11 -> PN532 MOSI
+ *   IO12 -> PN532 SS (CS)
+ *   IO13 -> PN532 IRQ
+ *   IO14 -> PN532 RSTO
+ *
+ * Wiring RF 433MHz (right side of KIT B):
+ *   IO19 -> RF TX DATA (nadajnik)
+ *   IO20 -> RF RX DATA (odbiornik)
+ *
+ * Touch recalibration: hold BOOT button during startup to erase saved
+ * calibration data and run the calibration wizard again.
