/* Song Chen Music — proposed redesign
   Palette sampled from her own recital photography: ebony stage, warm wood,
   and the deep concert red of her gown. One locked accent (that red).
   Type: Cormorant Garamond (Latin display) paired with a CJK SERIF for the
   Chinese pages, so the page reads equally elegant in both languages —
   a sans fallback on Chinese headings is exactly what makes bilingual sites
   feel like an afterthought. */
