/*
 * sections/resources.css — section "Recursos" (#recursos).
 *
 * DOIS LAYOUTS
 *
 * 1. Linear (padrão): sem JS, mobile, tablet e telas baixas.
 *    Cabeçalho + os 5 itens em sequência (imagem + texto). Trilha e dica ocultas.
 *
 * 2. Story / sticky (.is-enhanced): ligado por sections/resources.js quando
 *    RESOURCES_STORY_QUERY casa (≥ 960px de largura e ≥ 600px de altura).
 *
 *    .resources-scroll-area   altura = --resources-steps × 100vh (espaço de scroll)
 *      .resources-stage       sticky, 100vh — grid de 3 colunas:
 *
 *        colunas:  visual (34fr)  |  conteúdo (54fr)  |  progresso (12fr)
 *        linhas:   1fr  (respiro)
 *                  auto (cabeçalho fixo da section)
 *                  auto (conteúdo do item ativo)
 *                  1fr  (respiro + dica de scroll)
 *
 *      Os 5 .resources-step ficam EMPILHADOS na mesma área, via subgrid:
 *      .resources-steps e cada .resources-step herdam as linhas/colunas do stage,
 *      então a imagem de cada item cai na coluna visual (todas as linhas) e o
 *      texto na coluna de conteúdo (linha 3), abaixo do cabeçalho.
 *      A altura da linha 3 é a do maior texto → nada "pula" entre itens.
 *
 *    Visibilidade do item ativo: controlada pelo JS (Anime.js, opacity inline).
 *    Os inativos ficam só visualmente ocultos — continuam acessíveis a leitores
 *    de tela, na ordem do DOM.
 *
 * Painel escuro da coluna visual: .resources-stage::before (grid item).
