/* 掌媒科技 zhangmei.com v2 (2026-10-02): one stylesheet for every page.
   The colours are the site's own: night ink and the gold of the seal. The motif is the seal itself (a ruled square
   with ticks in its corners) and the ledger the site already speaks of: ruled rows, Roman numerals, set figures.
   The two Chinese faces come from the mirror the site has always used; nothing else is loaded from another host. */
