body had height:100% + overflow-x:hidden, which forces computed overflow-y to `auto` — turning body into its own scroll box at viewport height. window.scrollY then never moved, so the back-to-top button never appeared and window.scrollTo was a no-op. Apply overflow-x:hidden to <html> only; it propagates to the viewport (still clipping horizontal overflow) while leaving the window as the vertical scroller.
