   Clean rebuild of the original theme. Design tokens (colors, type sizes,
   spacing rhythm, alternating section backgrounds) are carried over from
   the original main.css so the site keeps its look. The old Bootstrap 3 +
   custom percentage-grid system has been replaced with plain flexbox/grid.
