/* Pretendard — self-hosted, no external CDN and no local() system-font
   lookup (this project's own bundled files only, always). Trimmed to the
   five weights the design actually requests anywhere in this file — 400
   (the unweighted default used almost everywhere), 500 (weight:450 on
   Page Builder BODY text resolves to the nearest available face at/above
   it per the CSS font-matching spec, which is 500 here), 600
   (.drive-folder-name), 700, and 800 (headings/CUT+PAGE numbers). woff2
   only — every browser this app targets supports it, so no woff fallback
   is carried. */
