# My Ultimate macOS Setup Script (v5 - Final)
#
# This script automates the setup of a new Mac. Below is a summary of
# all the actions it will perform.
#==============================================================================
#
# --- SCRIPT SUMMARY ---
#
# 1. Applications Installed:
#    - CLI Tools: node@18, caddy, supabase, direnv, gnu-getopt, postgresql, git
#    - GUI Apps: iTerm2, Cursor, Spotify, Logi Options+, Docker Desktop,
#                SmoothScroll, Rectangle, Shottr, AltTab
#
# 2. System Settings Applied:
#    - Reduces system-wide animations for a faster, snappier UI.
#    - Configures multiple displays to use a single, unified "Space."
#
# 3. Keybindings & Remaps:
#    - Swaps the Left Command and Left Control keys system-wide.
#    - Customizes text editing keybindings for word/line navigation.
#
# 4. App-Specific Configurations:
#    - AltTab: Configured to show windows on the current active space only.
#    - Shottr: Hotkey for area screenshots is set to Alt+1.
#    - iTerm2: Creates a new profile "Custom Profile" with keybindings:
#        - Command+C: Exit/Interrupt process (sends Ctrl+C signal).
#        - Shift+Command+C: Copy selected text.
