KM CYD-RIFE 3.1 CHANGES
=======================
- The full running screen is drawn only when entering the run screen or changing a setting.
- Once per second, only the MM:SS timer rectangle is cleared and redrawn.
- The SD search field, on-screen keyboard letters, program-list names and PREV/NEXT buttons use larger text.
- The running-screen BACK control is now QUIT.
- QUIT immediately stops wired PWM and Bluetooth audio, disables sweep, and returns to the SD program list.
- Frequency programs remain SD-only and are read from /frequencies.csv.
