# fastfetch — system summary fronted by the Nomarchy monogram. The logo is
# rendered from the vendored vector mark (modules/nixos/branding/logo.svg)
# via chafa at build time, recolored to the palette accent — so it's a
# compact, themed block-art logo that tracks the theme on each
# home-manager switch (rather than the oversized legacy ASCII).

  # (the SVG is an angled N); that is a logo-design limit, not chafa's.
