# FP6 offline charging (work/charging-mode): on charger-triggered boots,
# kill the boot splash and panel as early as software can — this hook runs
# right after splash_start in the initramfs (~6-10 s after power-on), vs
# the charging monitor's blank at ~16-20 s. The 0-5 s bootloader logo is
# ABL's and untouchable. Executed via `sh` by run_hooks (subshell, exit is
# safe); written to fall through harmlessly on any failure — a normal boot
# must never be affected.
