MAR Color 2.1 — LED wake refresh, 2026-09-18
Build: 2026-09-18-led-wake-refresh

Resends the physical RGB status on screen wake and refreshes an unchanged color
every second. Existing connection, activity and error colors are preserved.
Includes the previous local Wi-Fi all-channel scan build and its dashboard
features: live brightness, flexible firmware upload checks, channel terminals,
and separate Node 1/Node 2 indicators. Standard MAR firmware is unchanged.

Firmware build and LED regression tests passed. Physical sleep/wake validation
is pending; the reported intermittent hardware cause has not been confirmed.
BOOT retains its existing setup-hotspot behavior; the temporary portal status
clears after 60 seconds of connected Wi-Fi.

Update through the matching MAR Color portal or this site's settings-preserving
USB update. Full installation erases settings. Never flash an update BIN at 0.
