  /* ----- TYPOGRAPHY ----- */

  /* Font families */
  /* --font-jost is now historically named but maps to Nunito Sans.
     RATIONALE: The original Weebly site uses "Birdseye" (Avenir Next
     Ultra Light) as its display font. Jost was the original
     approximation. After visual comparison, Nunito Sans was chosen as
     a closer-feeling match (rounder letterforms, softer terminals).
     The variable name `--font-jost` was kept to avoid having to update
     every reference across pages.css / base.css / components.css /
     responsive.css. If you want to rename it for clarity later, grep
     all CSS files for `--font-jost` first to catch every usage. */
