Use the PPT/PPTX presentation I uploaded as the basis and create a new, professionally redesigned version. Preserve all of the original text, structure, slide sequence, and substantive content in full. Do not shorten or rewrite the text unless necessary. Your task is to improve exclusively the visual aspect and overall design. Style requirements: • Overall aesthetic: modern, elegant, premium minimalism. • Inspiration: Italy and the Mediterranean, but without obvious clichés or tourist stereotypes. • Atmosphere: lightness, spaciousness, natural light, calmness, and a sense of sunshine, sea, and high-quality Italian design. • Avoid: monograms, classical ornaments, ornate decoration, overloaded graphics, ostentatious decorative elements, gold frames, and outdated design. Visual principles: • Plenty of white space. • Clean composition and a clear information hierarchy. • Text should remain the main element, while graphics should complement it subtly. • Use fine graphic accents, light textures, geometric elements, and delicate illustrations or photographs with a Mediterranean aesthetic. • Maintain a consistent visual style throughout all slides. Typography: • Modern, clean sans-serif fonts; • Large headings; • Excellent readability; • Careful spacing and alignment. For charts, tables, and diagrams: • Redesign them in a modern, minimalist style; • Use a consistent color system; • Simplify the visual presentation without losing any information. The final presentation should look as though it were created by a professional Italian design studio: modern, light, aesthetic, and luxurious, but without visual clutter or excessive decoration. Take inspiration from the aesthetics of contemporary Italian brands, architecture, and Mediterranean boutique hotels: natural materials, light, simplicity, and a refined sense of taste.
