Blueberry Courseware Cover Slides

Objective: To create an elegant 16:9 widescreen PowerPoint presentation cover, with the theme of{argument name="topic" default="The Past and Present of Blueberries"} This presentation blends Chinese-style editorial layout with soft watercolor botanical illustrations. The canvas is a 16:9 landscape format with a warm, off-white handmade paper textured background featuring subtle fibers, faint stains, and minimal ink dots. The layout primarily uses a large, dark blue-gray Chinese title in the left third.{argument name="Chinese title" default="The Past and Present of Blueberries"} The title is displayed on two stacked lines with ample spacing, using a refined Song/Ming serif font. Above the title is a line of small uppercase "PPT COURSEWARE," prefixed with a tiny gold circular icon. Below the title is a thin gold line and a small serif uppercase English subtitle:{argument name="English subtitle" default="THE PAST AND PRESENT OF BLUEBERRIES"} The year is displayed in the lower left corner.{argument name="year" default="2026"} The page uses large serif numbers with a thin horizontal line below, followed by five Chinese category labels separated by vertical lines: "Origin | Evolution | Dissemination | Cultivation | Science | Life". Main image: Six visible blueberry-related watercolor elements are used throughout the page: a soft blue blueberry flower with a dark star-shaped calyx near the top center; a translucent blue leaf placed diagonally in the lower left; a small blueberry flower labeled "origin" near the lower left corner; a group of blurred blueberries (one with a visible calyx) near the lower right center; a cross-section of a blueberry labeled "cut" on the right (with pale flesh and tiny seed dots); and a blurred blueberry watercolor wash near the lower right corner. All fruit elements are kept in desaturated indigo, smoky blue, and grayish blue, with watercolor washes at the edges. Technical annotation details: Delicate gold and blue-gray chart markers are added: tiny crosses, dashed guide lines, small circles, target rings, and thin guide lines. Includes three small number labels: "01" near the top center blueberry cluster, "02" near the middle right blueberry cluster, and "01" as a page number in the bottom right corner. Add very small serif text labels "origin" and "cut". Right margin: Add a narrow vertical column of Chinese text on the far right.{argument name="vertical quote" default="How can a tiny blue fruit transcend time and space to encounter, get to know, and accompany human civilization?"} Next to or below it, add very small vertical capital English letters as decorative and editorial text about blueberries across time and space. Visual style: minimalist high-end academic presentation design, Chinese neo-literati aesthetics, botanical science notes, ample white space, soft ink-wash watercolor, tranquil deep blue and gray tones, accented with restrained antique gold. No figures, no photorealistic fruit, no vibrant colors, no watermarks.
