If an SSD1309 OLED is connected via Grove (GPIO1/GPIO2), it shows complementary info to the main bouncing clock display: View 0 (datetime): 24hr HH:MM:SS, day name, full date View 1 (battery): percentage, estimated voltage (~3.15–4.2V) Any keypress while the backlight is already on cycles between views. First press from idle wakes the backlight without cycling (expected behaviour — user confirms what they see before changing it). Glass2 is fully optional; app behaves identically without it.

Calling _g2_show once per loop iteration rather than only on the 100-frame tick — otherwise displayed seconds would be frozen for ~6s at a time. Battery view still only recalculates pct on the slow tick. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Update OLED once per second (on second change) rather than every 60ms frame — reduces I2C traffic ~60x and OLED power draw - Power off OLED when backlight dims to idle (burn-in prevention) - Power on and force immediate redraw when any key wakes the display Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
