/* The product site. One motif runs it: the tabbed folder. The app files its work in four groups (研究, 制作,
   发布, 复盘); the page files its sections the same way, each a folder in its own colour whose tab rises into
   the folder above. The colours come from the app icon: near-black, warm white and its pink bars.
   No web fonts, no external requests: the system faces render both scripts well on every Apple device. */
