Description

Describe the Bug

The default keymap configuration with LED config doesn't seem to make lights work. The hotkeys (FN2+[8,9,0,-]) doesn't do anything either.

Obins stock firmware lights up the LEDs

Research direction
Review the QMK firmware code for the AnnePro2/C15 keyboard, specifically the LED matrix configuration files (e.g., keyboards/annepro2/c15/rules.mk, config.h, and any LED related files like led matrix kb.c). Check if the default keymap includes LED configuration and if the hotkey definitions are correctly mapped. Compare with the Obins stock firmware behavior. Also, search for similar issues or recent commits that might have affected LED functionality on this keyboard.
