   About page — "Take the lift"
   The page is a building: lift doors open onto the lobby, every section is a
   floor with its real level, and a lift panel tracks where you are.
   Floors alternate ink and paper, like passing slab after slab.
   Scroll states (.is-in, lit dots, panel floor) come from js/about-page.js.
