Layout a griglia editoriale per slide PPT sul tema IKEA Cina

Build an editorial PPT visual system framed by a modular and baseline grid: use unequal-width columns and strict alignment to carry the title, body text, data, and focal visual; use the Gestalt principles of common region and continuity so that color blocks, cropped images, and linear symbols form clear groups and a smooth flow; use dynamic equilibrium so the large-scale text on the left counterbalances the vertical visual mass on the right across a distance; use Itten's extended contrast to control the tension between the restrained large-area ground color and the small-area high-saturation information blocks. Draw on Josef Müller-Brockmann's mathematical grid and objective hierarchy to stabilize all pages, on Alexey Brodovitch's radical cropping, white-space pauses, and image-text dialogue for editorial rhythm, and on Paul Rand's geometric wit and concise line drawing for warm memory points; the three govern structure, image rhythm, and symbolic accent respectively, without mechanical replication. Set five substitutable color roles: background occupies 55%–65%, highest lightness, low saturation; structure and text occupy 10%–15%, lowest lightness; information blocks occupy 20%–30%, mid-high lightness and mid-high saturation; focal image occupies 8%–15%, retaining natural light-and-dark with light tone unification; accent color no more than 3%, at highest saturation close to structural edges to trigger simultaneous contrast. The theme or brand color must be mapped by role all at once, keeping area, lightness order, saturation gradient, adjacency relations, and shadow legibility unchanged. Pages use a composite editorial grid, with a wide information zone and narrow visual zone forming an asymmetric skeleton; primary reading proceeds from the oversized title, to the focal visual, to body or data; body text strictly holds to column lines and the baseline, image and a few symbols may cross one column line to create the single break, retaining ample outer margins and inter-paragraph space, with one main focus per page. The background is a clean matte plane with no global texture; rectangular images get hard-edge cropping, focal images get precise cutout, first lay down large-scale geometric color fields, then overlay images, and finally add uniform thin line arcs, radial short lines, and free polylines, with rounded ends and local overflow; images use soft natural light and clear contact edges, with no heavy shadows. Fonts use a skeleton-compatible low-stroke-contrast sans-serif system, titles at light-to-regular weight, oversized size, tight leading, and refined kerning for a wide letterface, body text at regular weight and higher leading to sustain continuous reading, data enlarged but not thickened; CJK and Latin letterfaces calibrated by optical density in baseline, weight, and size, with only a single geometric counting symbol embedded at the end of the title, maintaining restrained, crisp, rational, warm, agile, and trustworthy. —————— Topic: Why IKEA no longer sells well in China Rich in knowledge points vary each page's layout to avoid uniformity 10 slides total Aspect ratio 16:9
