/* WordPress / Elementor compatibility: what a WordPress theme and Elementor add around this page, put back to what the
   page was designed on. Inert in a plain browser.
   1. The theme styles <body> and every heading (Twenty Twenty-Five: body weight 300 and -0.1px tracking; h1-h6 weight 400,
      -0.1px tracking, line-height 1.125, preset sizes). Restore the browser defaults at element level; every class rule
      above still wins (0,1,0 beats 0,0,3).
   2. The Elementor container that holds the sections keeps the kit's default padding and gap whenever its generated
      post CSS is missing; zero them.
   3. Elementor resets every <figure> margin at (0,4,1); repeat its prefix on this page's own figure margins. */
