   Pure white ground, neutral cool greys only (no beige/off-white),
   soft near-black text. Latin type in Times New Roman, Japanese
   in a Mincho serif — one unified serif voice across the site.
   The strung-bead motif (rendered in shades of grey) is the one
   recurring signature: nav underline, the seam between image and
   text on work pages, and the news timeline.
