// Important: globby/fast-glob doesn't guarantee order of the returned files.
// We must sort the pages so the input list to rollup is stable across
// builds - otherwise different input order could result in different exports
// order in shared chunks which in turns invalidates the hash of every chunk!
// JavaScript built-in sort() is mandated to be stable as of ES2019 and
// supported in Node 12+, which is required by Vite.
