/* 图外 · China, Place by Place — site styles.
   Color: fixed by the VI on Notion page 12 — 宣纸白 paper, 松烟墨 ink, 龙泉青 celadon, 釉青浅底 glaze,
          朱砂红 cinnabar (brand seal, primary action, focus only), 淡金 gold (route nodes, rules on dark).
   Type:  Libre Caslon Display for headlines, Libre Caslon Text for story prose, Public Sans for interface,
          Noto Serif SC (Song) for Chinese.
   Signature: Chinese place names set vertically, like a plaque or a stele inscription, beside the
          English. It appears on the cover, place tiles and place pages; everything else stays quiet.
   Layout: left-aligned; full-bleed cover photo with an overlapping paper panel; one reading column
          (~38rem) for stories; a gold-ruled timeline for the journey. */
