   Everything above describes WHAT the components are. This final layer decides

     (a) assigns the two type families to their correct jobs;
     (b) applies the recurring graphic marks that make an Atlas page
         recognisable at a glance;
     (c) tightens hover / focus behaviour to a restrained, non-SaaS cadence;
     (d) aligns numerals so quantitative content reads as data, not as prose.
