/* Bangla typography — applies only while <html lang="bn">.
   Fonts follow the design system: Hind Siliguri for headings, Noto Sans Bengali for body/UI.
   Bengali tracking is 0 (letter-spacing splits conjuncts), leading is open, and body sizes sit
   about one step above the English scale because Bengali glyphs read smaller at the same px. */
