   UI HTML sobreposta à cena 3D interativa da usina de biogás
   (#biogasScene, ver js/biogas-scene.js). Fica em arquivo próprio por
   ser um componente grande e autocontido — progresso, navegação,
   tooltip, painel técnico e fullscreen.

   ÍNDICE
   1. Camada base (.scene-ui) + barra superior (progresso/toolbar)
   2. Tooltip de hover
   3. Barra de navegação inferior (anterior/próximo)
   4. Painel técnico lateral (desktop) / bottom sheet (mobile)
   5. Modo fullscreen
