# EULE assistant keep-alive - keeps the work computer ready for the scheduled Postkast runs.
#
# Run by a Windows scheduled task (registered by paigalda.ps1) on weekdays every
# 15 minutes from 08:50 to 18:50. Each run:
#   1. resets the idle-sleep timer, so the computer does not fall asleep during work hours
#      (the task itself is allowed to wake the computer);
#   2. starts Outlook Classic minimized if it is not running;
#   3. starts the Claude desktop app if it is not running (the cloud runs reach Outlook through it).
# It never reads, sends or changes mail. Log: %LOCALAPPDATA%\EULE\hoia-ylal.log (last 300 lines).
#
# Kept ASCII-only on purpose: Windows PowerShell 5.1 reads downloaded scripts
# without a BOM as ANSI.
