   Numbers below About are measured from ui/首页-关于我们2.0.png
   (1920 × 7077). The 0819 sheet (older ui/首页-关于我们.png, 1920 × 5627) is the
   source for Hero / Creative / Global / Clients, which that round did not
   redraw. Mockups can only be measured by *ink*, so each ink coordinate was
   converted to a CSS line-box coordinate with tools/inkoffset.py
   (HarmonyOS Sans SC: asc 928 / desc 244 / upem 1000).
