- * MUST hold inactive (HIGH) or SPI bus fights the LCD → edge garbage:
- *   T_CS  → GP6   (touch XPT2046 CS)  — or tie to 3.3V if unused
- *   SD_CS → GP7   (microSD CS)        — or tie to 3.3V 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.
