/* ── 中文字體:仿 Apple 官網嘅 SF Pro TC(10-14 Alex)──────────────────────────
   SF Pro TC 係 Apple 官網專用、冇公開授權嘅網頁字體,唔可以用。佢 = 蘋方 + 兩樣微調
   (skywt.cn 拆過):① 漢字縮細啲,同 SF 西文混排唔會大過英文;② 全形標點收窄到半形。
   呢度喺蘋方上面做返:用 unicode-range 淨係接管中文同全形標點,西文照落 SF;
   size-adjust 縮漢字;halt 收標點(蘋方支援 halt,palt 量過冇變:全形逗號 100 → halt 50)。
   Mac / iPhone 本身有蘋方,唔使下載任何字體;Windows 等冇蘋方就落後備系統中文字體。 */
