Description

Describe the Bug

When computer sleeps, master board LEDs turn off while slave LEDs remain lit. These are the key switch LEDs for backlighting, not the additional rgb extra lighting

Several ideas not knowing anything beyond keymaps... master isn't notifying slave of sleep master isn't sending backlight off instruction to slave slave isn't turning off backlights in response to sleep notification

Contributor guide

Research direction
Investigate the QMK split keyboard sleep code, specifically how the master notifies the slave about sleep state and backlight commands. Trace the `backlight toggle` or `backlight set` functions on the slave side.
