   topplay020 · Portfolio
   Five themes, each a ground and a low-poly gradient that runs down the page. Urbanist + DM Mono + IBM Plex Sans Arabic.
   Logical properties throughout, so EN (LTR) and AR (RTL) share one stylesheet.
   The page sits on top of a fixed WebGL canvas: at 1000px and up the words hold
   one column and the tower stands in the free side; below that, each section
   opens with a transparent "window" onto the tower and its words sit on solid ground.
