   About Ying Wa
   1. Hero      – one large photograph (the page's Featured Image), editorial type
   2. Story     – a statement that "writes itself" as you scroll, on faint campus brick
   3. Index     – an editorial index of the 11 sections; a photo follows the cursor
   Every class is prefixed .ab- so nothing here touches other pages.
