 *   LED  → GP22
 *   SD_CS→ GP7   (hold HIGH if unused)
 *
 * Touch XPT2046 — on THIS panel T_* does NOT share tracks with LCD
 * (continuity check failed). Wire all 5 touch pins to Pico:
 *
 *   T_CLK → GP18  (jumper to same net as LCD SCK)
 *   T_DIN → GP19  (jumper to same net as LCD MOSI)
 *   T_DO  → GP16  (touch DO — NOT LCD SDO if they are separate pads)
 *   T_CS  → GP6
 *   T_IRQ → GP8
 *
 * During a touch sample we bit-bang CLK/DIN/DO; LCD SPI is restored after.
