/*
  O Thiago Comunica — Desvendando a Geração Z
  main.css v2.0 — consumes tokens.css. Pure CSS, no framework, no CDN.

  Built to ui-guide v2.0. Three structural ideas carry the whole page:
    1. VIOLET IS LIGHT — halos/pools/lit hairlines live on the background plane.
       Buttons, chips, badges and icons stay flat solid. No gradient inside any UI object.
    2. TWO MOTIFS FROM THE LOGO — hexagon = system/method; speech bubble = conversation.
       Bubbles use an asymmetric radius; that asymmetry is what stops the page reading as boxes.
    3. ONE SPATIAL LOGIC PER SECTION — max two composition devices each (guide §6.2).
