The document vault and the admin area each carried a formatBytes; the same backup read 1.25 MB in one and 1.2 MB in the other, and only the vault knew gigabytes. The vault rule (one decimal below 100, up to GB, digits in the reader's locale) now lives in src/lib/format/bytes.ts and takes the locale, so the server-rendered share page uses it too. A test holds the definition to that one module.
