/* =============================================================
 * Catálogo › Vendas › Biblioteca técnica (15/10/2026) — biblioteca-tecnica-ui.js
 * Manuais, diagramas, fichas técnicas e informativos numa tela só, para o vendedor.
 * Só tokens da pele 2026 (--bg, --panel, --line, --ink*, --accent*, --chip, --red*, --r-lg, --r-pill): nenhuma
 * cor fixa, então o modo escuro vem pronto (sem regerar o portal-2026-dark.css; o #000 das máscaras da faixa de
 * abas não pinta nada). A cor do grupo (dado da Gestão da Biblioteca) aparece só no filete ao lado do nome.
 * Notebook primeiro (1366 × 768, gaveta fechada), um scroll só (o da página), sem rolagem horizontal de 320 a 1920.
