/* Breakout centring — viewport-centred, independent of the left-aligned reading

   NOTE: .post-content .kg-card{margin:36px 0} (higher specificity) zeroes any
   margin-left on these figures, so we CANNOT centre via margin — we use only a
   transform. The reading column's left edge is 32px inside the centred 940 frame,
   i.e. container-left = 50vw − 438px (438 = 940/2 − 32) once the frame is capped
   (viewport ≥ 940). translateX(438px − 50%) then puts the element centre on the
   viewport centre for ANY element width and any column width. Below 940 the frame
   tracks the viewport, so container-left = 32px and the offset is (50vw − 32px). */
