+// M5Paper Stock Ticker  -  M5Paper v1.1 (classic ESP32) edition
+// =======================================================
+// Target: M5Paper ESP32 Development Kit V1.1 (SKU K049-B)
+//   - ESP32-D0WDQ6-V3, 540x960 @4.7" e-ink (IT8951E), BM8563 RTC
+//
+// Difference vs. the main sketch (../m5paper-stockticker.ino):
+//   The classic M5Paper's low-power management differs from newer boards,
+//   so sleep/wake is handled through M5Unified's board-aware power API
+//   (M5.Power.deepSleep) instead of a raw esp_deep_sleep_start() with a
+//   manual radio teardown. deepSleep() puts the e-ink panel to sleep and
+//   drops the board to its rated ~10uA deep-sleep state, waking on the
+//   ESP32 RTC timer (any duration, so overnight/weekend sleeps are fine).
+//
+// Everything else - portfolio, market-hours logic, layout - is identical.
+// Copy your config.h (and images.h) into this folder before flashing.
