Two vertically connected rounded rectangular panels are anchored by extremely thick, slightly undulating black hand-drawn outlines, with white buckles crossing the panel edges, forming striking paired modules and clear vertical rhythm. Content is organized using Gestalt proximity and layout zoning, with each panel internally divided into a stable left-image/right-text column, balancing left and right weights, titles and information read top-to-bottom in the right column; the overall visual center falls on the junction of the two panels and their respective prominent large titles, keeping the page header area independent with logos and main title. Images and text connect via juxtaposition and backing: the left side is reserved for character or theme illustrations, placed on irregular rounded clean light-colored bases; the right side uses prominent large characters to lead multiple lines of explanation, accompanied by small line-drawing symbols adjacent to text to indicate content. Text hierarchy is always distinct, large titles are thick and striking, explanatory text is thinner with generous line spacing, small text and symbols create rhythm points; glyph construction is upright and readable, with clear counters, crisp endings, and compact faces complementing handwritten images, maintaining this hierarchy regardless of text volume; when text is insufficient, secondary small text is supplemented based on the theme. Text edges are flat and clear, forming a clean typography layer outside the hand-drawn lines. Whitespace includes gaps between panels, backing whitespace around image bases, reading gaps between text lines, and pauses between header and body; each remains spacious, allowing thick frames, illustrations, and titles to stand out clearly. Illustration content is provided by the appended theme, adopting a complete, concentrated, slightly tilted hand-drawn composition within the left column, with simple main outlines, light dynamic details, and upright load-bearing parts; content density is about half-frame, mainly concentrated in the left column of each panel, the rest being white or light-colored rounded bases, flat panel color blocks, and bottom whitespace, generating no scenery. Uses a composite of techniques: outlining frames and characters with continuous, slightly shaky thick black lines; spreading large panel areas and local illustration colors with clean, smooth digital flat coloring; pressing information areas with crisp text typesetting; overall resembling an illustration arrangement synthesized from hand-drawn lines, computer flat coloring, and clear typesetting. Color scheme maintains a high-brightness keynote, colors vivid, saturated but not glaring, the most intense color surfaces fall within the paired panels echoed by character locals; pairing warm light backgrounds with varying brightness levels of light color surfaces, stabilizing layers with strong black-and-white line text contrast. Overall warm and cheerful, friendly and energetic, resembling matte digital color blocks combined with dense marker lines; hue follows the theme, but brightness/darkness, thickness/thinness, saturation/dilution, warm tendencies, and cheerful friendly psychological feelings maintain this personality regardless of theme. Overall temperament is light, friendly, and orderly. Appended theme, accurate text, usage, and aspect ratio take priority; grouping of upper/lower panels, left-image/right-text, thick black hand-drawn borders, image backing, clear text hierarchy, and high-brightness warm-thick color schemes remain unchanged.
