   Serif display type, typewriter data, hairline rules. Feature cards and
   information blocks use a clean, evenly balanced card system throughout,
   consistent padding, consistent radii, consistent alignment, instead of
   fused matrices and asymmetric spec sheets. Only the functional hooks
   (ids/classes/data-attrs) that script.js reads are kept in place.
