Scattered Composition Knowledge Card

Goal: Create a vertical educational knowledge-card poster explaining {argument name="headline text" default="分散构图"} with a dark, modern graphic-design style, about scattered composition in visual layout.

Canvas: Portrait 3:4 poster, black background with subtle paper grain, high contrast, generous empty space, clean Swiss/modern editorial layout.

Main title area: Place a very large two-line Chinese headline in the upper left. The first line is off-white, the second line is lavender-purple. Under it, add the English subtitle “SCATTERED COMPOSITION” in uppercase lavender. Below the subtitle, add a short lavender horizontal rule and a left-aligned Chinese explanatory paragraph: “将视觉元素有意分散在画面各处，形成多个视觉焦点，营造开放、轻盈与多向的视觉体验。”

Visual structure: Scatter geometric elements across the poster, using asymmetrical spacing and multiple focal points. Include exactly 15 main graphic elements: 1 large yellow circle near the upper right, 1 medium purple circle at the center-right, 1 small orange circle near the middle, 1 teal square in the lower-left quadrant, 1 small pink square at the right-center, 1 small purple circle near the lower center-left, 1 large off-white hollow ring in the lower-right quadrant, 5 white plus signs distributed around the page, 1 yellow plus sign near the lower center, 1 purple 3-by-3 dot grid near the upper right, and 1 off-white 3-by-3 dot grid near the lower center-left.

Callouts: Add exactly 3 dotted leader-line annotations with small endpoint dots. Callout 01 points to the large yellow circle and uses yellow label text: “视觉焦点 01”, followed by white body text: “大面积色块吸引视线，建立主要焦点。” Callout 02 points to the medium purple circle and uses purple label text: “视觉焦点 02”, followed by white body text: “中等元素与留白结合，引导视线自然停留。” Callout 03 points to the small orange circle and uses orange label text: “视觉焦点 03”, followed by white body text: “小面积高对比元素，成为次级视觉锚点。”

Tip section: In the lower left, add a small purple lightbulb icon, the label “技巧提示” in purple, and the body text “通过大小、色彩、形状、方向的变化，在分散中建立联系，在留白中制造节奏。” Add a thin off-white underline below this block.

Legend: In the lower right, beside the large hollow ring, create a compact legend with exactly 4 rows. Row 1 has a yellow 3-by-3 dot icon, Chinese label “变化”, and English label “VARIATION”. Row 2 has a purple wavy-line icon, Chinese label “节奏”, and English label “RHYTHM”. Row 3 has a teal plus icon, Chinese label “呼吸”, and English label “BREATH”. Row 4 has a pink outlined square icon, Chinese label “开放”, and English label “OPENNESS”.

Visual style: Minimalist Chinese design infographic, bold typography, flat vector shapes, matte texture, sharp edges, dotted connector lines, color palette of black, off-white, lavender purple, yellow, orange-red, teal, and pink. Use strong negative space and no borders.

Constraints: Keep the poster text legible, maintain the exact counts of graphic elements, avoid extra illustrations, avoid photorealism, avoid watermark or logo.
