   TW Market — Market-wide Margin / Short Balance (大盤融資融券餘額)
   Focus = market-wide margin balance (億元) line + short balance (張) on a
   secondary axis, plus the per-stock margin-change hotlist (SSR interlink).
   Layout copied from the sibling market/*.css pages (futures_retail_long_
   short_ratio.css baseline + institutional.css hotlist recipe) — only the
   `.xlink` header link is new.
   ALL color / radius / shadow / motion via main.css tokens.
