/* UOMAS website styles — one file for all pages.
   Sizes copied from the original Squarespace site, measured at 1440, 1920 and 2560px wide and on a 390px phone.
   Like the original: content sits in a centred column of max 1400px, and vertical spacing grows a little
   with screen width (that's what the "px + vw" values do). */
