/* Symbols-only Nerd Font, served from jsDelivr's GitHub mirror.
   This font contains only the icon glyphs in the Unicode Private Use Area
   that the panel-header icons use (CPU, Memory, Disk, Network, etc.).
   Declared with `unicode-range` so the browser only downloads the file
   (~500 KB) when one of those codepoints actually needs rendering — the
   homepage glyphs trigger it, every other character routes to JetBrains
   Mono first. `font-display: swap` means the rest of the page renders
   immediately even while the font is loading; icons appear as tofu for
   the ~200 ms it takes the font to arrive, then snap in.
   To rotate to a newer Nerd Fonts release, bump the version tag in the
   URL below — releases live at https://github.com/ryanoasis/nerd-fonts. */
