# Description:
# - Set xrandr DPI for HiDPI displays (immediate effect).
# - Update xprofile to persist DPI across reboots.
# - Update ~/.Xresources for terminal fonts and DPI.
# - Update dwm/st config.def.h files for git-safe persistence.
# - Creates device flag file for permanent laptop designation.
# - Backups are made before modifying files.
# - Created for Macbook Pro 2015 13" Retina (Model A1502)
