/* ══════════════════════════════════════
   FOOTER — the portfolio button, under everything
   Shaped as JOGAR (the cta variant), as far from the screen's edges as JOGAR
   is (19px; 480px wide at most) and as far from the settings above; its
   background is the portfolio's own shader, its own green
   (js/portfolio-shader.js), its
   words in the portfolio's greeting type ("boa noite": the system's sans,
   900, tight). Without WebGL: a still gradient in the same colours.
