Modern Lemon Uses PPT Cover

Objective: Create a simple and modern Chinese PPT cover with the theme of {argument name="topic" default="The Wonderful Uses of Lemons"}, adopting the international Swiss style of modular grids, fresh lemon yellow accents, soft light color blocks, and bright, healthy/lifestyle editing style.

Canvas: 16:9 widescreen slide, off-white background, ample whitespace, clear typography, and no watermarks. Employ an asymmetrical balanced layout: large-area text layout on the left and a large-sized rounded-corner photo composition on the right.

Layout: The left side includes stacked titles and four feature cards. The right side contains a large rounded-corner lemon photography panel occupying approximately half the slide width. A black and yellow page tab bar is located in the lower right corner. Add subtle vertical baselines/grid scales along the bottom edge.

Text Content: The main title uses a very large, bold, black Chinese font: {argument name="headline text" default="The Wonderful Uses of Lemons"}. Add a short fluorescent yellow underline below, followed by the subtitle: {argument name="subtitle text" default="10 Pages of Modern Information Presentation"}. Below the subtitle, place a rounded-corner fluorescent yellow capsule-shaped label containing 4 categories separated by centered dots: {argument name="category text" default="Cleaning · Diet · Preservation · Beauty"}. The bottom page tab displays a large black “01” on a fluorescent yellow rounded rectangle, and “Cover” in white font on a black rounded rectangle.

Feature Cards: Horizontally arrange 4 rounded-corner light-colored cards below the category capsule, each containing a simple black line icon, a bold Chinese label, and two lines of description: 1) Sparkling spray bottle icon, label “Cleaning,” description “Natural decontamination / Safe and environmentally friendly”; 2) Bowl of lemon slices icon, label “Diet,” description “Add flavor / Enrich nutrition”; 3) Refrigerator icon, label “Preservation,” description “Extend freshness / Reduce waste”; 4) Side face with sparkle icon, label “Beauty,” description “Natural care / Brighten skin.” Card colors from left to right are: light lemon yellow, light purple, light blue, light lemon yellow.

Right-Side Image Composition: Use fresh, high-key lemon photography taken on a light-colored stone surface: a whole lemon with green leaves in the upper right corner, a half lemon with visible juicy radial pulp in the foreground center, a lemon wedge in the lower right corner, and a soft-focus yellow lemon in the background. Overlay modern rounded-corner translucent geometric panels: a vertical light purple rounded rectangle with a small hand-drawn lemon doodle in the upper left corner, and a large translucent fluorescent yellow rounded square/rectangle with green leaves interspersed covering the lower left corner of the photo. Maintain large rounded corners for the photo.

Decorative Details: Add a 3x3 dot pattern in the upper left corner, consisting of 9 dots, alternating lemon yellow, light purple, and light blue. All icons should be single-line black, typography should be bold and modern, emphasizing alignment and leaving ample whitespace. Avoid adding extra text or additional cards.
