/* O botão deslizante do site — a pista, o preenchimento e o botão.
 *
 * **Movido de `home.css`** quando a tela de pesos por pergunta passou a usar o mesmo
 * controle. O comportamento vive em `ev-slider.js`, e o tamanho do botão (18px) é
 * combinado entre os dois: `TAMANHO_DO_BOTAO` lá é este `width`/`height` daqui, e é o que
 * decide de que lado o clique na pista empurra. Mudar um sem o outro não dá erro — só faz
 * o clique perto do botão ir para o lado errado. */
