+// MPI Bilingual Chinese-English Template
+// ============================================================
+// A simple Typst template for bilingual Chinese-English Buddhist
+// texts, matching the 静心学堂丛书 formatting guide.
+//
+// Fonts (all available from Google Fonts):
+//   - Chinese body: Noto Serif CJK SC
+//   - English body:  Noto Serif  (Times New Roman substitute)
+//
+// Format highlights:
+//   - Body size: 10.5pt (Chinese 五号)
+//   - Line spacing: 1.5em
+//   - Justified body text with 2em first-line indent
+//   - Headings unnumbered, with 1.2em block spacing
+//   - Footnotes in 8pt, left aligned
+// ============================================================
