/* -----------------------------------------------------------------
   Punctuation override for serif headings.
   ---------------------------------------------------------------
   Our --font-serif uses Noto Serif TC, a CJK-first font that bakes
   wide right-bearing into Latin punctuation glyphs. That makes a
   curly apostrophe (U+2019) followed by a letter look like there's
   a literal space between them — e.g. "Who’s" rendering as "Who’ s".
   By declaring our own font-family alias whose unicode-range covers
   just the offending punctuation, Latin fallbacks (Georgia, Times)
   handle those code points while Noto Serif TC keeps everything
   else. This is invisible for non-Latin pages where the CJK glyphs
   are needed; it just stops Noto from rendering a left-quote, right-
   quote, or apostrophe with CJK whitespace.

   Code points included:
     U+2018 left single quote       ‘
     U+2019 right single quote / apostrophe  ’
     U+201C left double quote       “
     U+201D right double quote      ”
