/* --- CJK ranges -------------------------------------------------------
   Regular (400): 华文中宋 / STZhongsong — the medium-weight serif the Typst
   site already uses, kept as the body face.

   Bold (600/700): a slightly heavier serif only. 黑体 / SimHei is deliberately
   NOT in the stack — it is a solid-black sans and reads far too heavy next to
   中宋. When no real semibold/bold serif is installed these faces resolve to
   nothing, the CJK glyphs fall through to the regular 中宋 in the font-family
   list, and the browser synthesises a light bold — which is the intended look.

   To go all-serif with a lighter body instead (SimSun body, 中宋 for bold),
   swap the 400 src to local("SimSun"), local("Songti SC") and the bold srcs to
   local("STZhongsong"), local("华文中宋").
