/*
 * Documentacao do metodo Expx.
 *
 * A paleta herda o azul do painel (--vscode-focusBorder #0078d4 / #005fb8) porque
 * a doc e o produto sao a mesma coisa vista de dois lugares. O resto e proprio:
 * ground levemente quente, tinta com viés frio, e a familia IBM Plex — desenhada
 * para documentacao tecnica, e nao a escolha default.
 *
 * Tres estados de tema, nao dois: :root e a paleta clara completa;
 * prefers-color-scheme cobre o padrao "sistema"; [data-theme] vence o toggle
 * nos dois sentidos. Nenhuma cor nasce dentro de media query.
