Usage

Using the theme

Terminal Requirements

For best results, ensure your terminal supports truecolor (24-bit color):

• Check support: echo $COLORTERM (should output truecolor or 24bit)
• Enable if needed: export COLORTERM=truecolor

Most modern terminals (iTerm2, Alacritty, Kitty, Windows Terminal, GNOME Terminal) support this by default.
