   font-display: optional, not swap, on all three: swap always shows
   the fallback font first then reflows to Quicksand once it loads,
   which is a real layout shift if that swap lands after the page is
   already scrolled past that heading - reported as "text jumps" on

   font is already cached/ready almost immediately, trading an
   occasional fallback-font render for zero shift. */
