/* Self-hosted, and this is not only about avoiding a third-party request.
   Google Fonts serves JetBrains Mono as a subset that stops short of the box
   drawing range (U+2500–257F), so the banner frame, the `tree` output and the
   neofetch rule all fell through to a fallback font whose advance width is
   0.55em instead of 0.6em. Every box in the shell was quietly sheared by that
   difference. One font, one advance, no shear. */
