/**
 * Turns Simple Icons' 3,400 SVG files into one map of slug → path data.
 *
 * The package ships a file per icon and 15MB of SVG wrapper around what is
 * really a single `d` attribute each. This keeps the attribute and throws the
 * rest away, so the app carries about a megabyte instead of fifteen.
 *
 * The output goes to public/ rather than src/: it is fetched once at runtime
 * instead of being parsed into the JS bundle at every startup.
 *
 * Run `npm run icons` after upgrading simple-icons. The output is committed,
 * so a build never depends on this having been run.
