   Nhập Lưu - self-hosted fonts (decision D-34)

   NOT the Google Fonts CDN. The handoff hot-linked fonts.googleapis.com; that
   does not ship. It would put a third-party CDN on the critical path of a
   monastery registration form, leak every visitor's IP to Google, and silently
   degrade the typography wherever the CDN is slow or blocked.

   Both families were VERIFIED in a real browser at 400/500/600 against a
   Vietnamese sample (chiều, ắ ẳ ệ ỗ ợ ự ữ ẩ ẵ ọ, Nhập Lưu, Bước 2 trên 7,
   Sức khoẻ) and every diacritic composes correctly. The same test carried
   Georgia as a known-bad control and it failed exactly as expected: "chiều"
   rendered with the tone mark detached from the vowel. That is what makes the
   result trustworthy - the method demonstrably detects the fault.
   Evidence: design_mockups/registration/evidence/VERIFIED-fonts-vietnamese-diacritics.png

   Both are VARIABLE fonts: one file per subset covers the whole 400-600 range,
   so there is no separate file per weight.

   The vietnamese subset is listed FIRST in each family. Order does not change
   which file the browser picks (unicode-range decides that), but it makes the
   priority obvious to the next person reading this file.
