/* Sprint J (2026-06-02) — self-hosted font declarations.
 *
 * Latin variants are tiny (~14KB each); they're declared without
 * unicode-range so they load on any page that references the family.
 *
 * Chinese (chinese-simplified subset) variants are 1.1-1.5MB each; they're
 * declared WITH `unicode-range` so the browser only fetches them when a
 * CJK glyph in the listed range is actually rendered. For an English-
 * primary site this means CN users incur a one-time download and English
 * users never download the 4-5MB of CN fonts at all.
 *
 * font-display: swap means the system font shows immediately and the
 * custom font swaps in once loaded — no flash of invisible text.
