Elegante Copertina per Presentazione Botanica

An elegant 16:9 widescreen presentation slide cover with a botanical academic aesthetic, set against a warm off-white handmade paper texture with subtle fibers and faint ink speckles. Layout and Typography: - Left third: Large Chinese title in dark blue-gray serif (Song/Ming style): "[蓝莓的\n前世今生]" in two stacked lines with generous line spacing. Above it, a tiny gold circular icon followed by small uppercase text "PPT COURSEWARE". Below the title, a short delicate gold line and the English subtitle in small serif capitals: "[THE PAST AND PRESENT OF BLUEBERRIES]". - Bottom left: Large serif year "[2026]", underlined by a thin line, followed by small category tags: "起源 | 演化 | 传播 | 栽培 | 科学 | 生活". - Far right margin: A narrow vertical column of small Chinese text: "[一颗小小的蓝色果实，如何跨越时间与空间，与人类的文明相遇、相知、相伴。]", alongside decorative small vertical English text. Botanical Illustrations: - Exactly 6 watercolor blueberry elements in desaturated indigo, smoky blue, and gray-blue with feathered edges: 1. Large soft blueberry bloom near the upper center with a dark star calyx. 2. Translucent blue leaf angled diagonally below-left of it. 3. Small blueberry bloom near the lower left labeled "origin". 4. Clustered pair of soft blueberries near lower middle-right. 5. Circular blueberry cross-section on the right labeled "cut" showing pale pulp and tiny seeds. 6. Small fuzzy blueberry watercolor wash near the lower right. Annotation & Diagram Accents: - Fine gold and blue-gray scientific marks: tiny registration crosses, dotted guide lines, delicate circles, thin leader lines. - Small numeric annotations: "01" near the upper-center berry, "02" near the middle-right cluster, and slide page number "01" at the bottom right corner. Style: - Minimalist Chinese new-literati aesthetic, scientific field notes, muted navy and gray palette with subtle antique-gold accents, generous negative space. No photorealism, no bright neon tones, no people, no watermark.
