Create one wide landscape 16:9 presentation concept page for the fictional tea brand 山间茶事. Match the warm daylight, paper tactility, tea-brown and muted rust palette of reference image 1, using reference image 2 only for the idea that packaging can express a brand system; do not borrow its green palette, matcha claims, brand, or dense grid. Tell the packaging-structure story through a beautifully photographed, partially opened paper box and a clear, graceful exploded arrangement of its imagined layers: an abstract mountain-pattern sleeve, inner box holding tea samples, cotton-paper sachets, and a brew-instruction card. Keep the scene tactile and editorial rather than a technical factory drawing. No measurements, actual material specifications, manufacturing claims, or extra logos. Use legible Chinese labels and render exactly these lines, each once: “拆开一盒,读懂包装层次” “从纸套到提示卡,逐层讲清设计意图。” “纸套:抽象山形纹” “内盒:收纳茶样” “棉纸袋:独立茶样袋” “提示卡:冲泡步骤” “包装结构示意 · 虚构概念” No additional readable text. The structure is a proposed concept, not a production package specification. Warm window light, quiet editorial art direction, 16:9 wide slide.
