   Poppins is a geometric display font — great for headings but
   reads formal and dense in long copy. Inter is a humanist
   sans-serif designed specifically for screen reading: open
   apertures, neutral letterforms, excellent at small sizes.
   All <p> elements get Inter with generous line-height and
   slightly tracked-out spacing for a natural, editorial feel.
