A hold now turns the button blue with FIXING <what> while the fix runs, then CHECKING for 20 s (green if it worked, back to the alarm if not), orange FIX FAILED if the command failed, and grey NOTHING TO FIX or JUST TRIED / WAIT 1 MIN so a hold always visibly registers. The page redraws as soon as a command arrives instead of on the next 1 s tick. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
