/* Velocity 360 marketing site.
   One 1200px column on the app's cool warehouse-grey ground. Every product picture is a real screenshot of the app
   (tools: see site/README.md), framed like a window; section labels are set in the mono face, like location codes.
   Colours and faces are the app's own (src/Velocity360.UI/wwwroot/velocity360.css); change them there first. */
