   PRESNSE — INDUSTRY · CHINESE MEDICINE  ·  bespoke SIGNATURE layer
   ----------------------------------------------------------------
   This file holds ONLY the page's invented signature module — the
   bilingual EN / 繁 search-system split. Everything else reuses the
   shared .ind-* language in industry.css. Consumes tokens from
   foundation.css ONLY — no raw colour.

   SIGNATURE motif (10a · the one mid-page dark band): two light panels
   glow on the dark substrate — an English query column beside a
   Traditional Chinese query column for the SAME patient intent. The
   columns surface different SERP makeup, different competitors, and
   different volumes — proving the two languages are separate search
   systems, not translations. Lime marks the parity verdict / status.
