Goal: Create a wide-format editorial hero banner about , using a puzzle metaphor to showcase AI coding, visual design, and missing functionality. Canvas: Ultra-wide horizontal banner, aspect ratio about 5:2, dark charcoal tech background with faint grid lines, subtle blueprint marks, tiny dot matrix, and thin circuit-like guide lines. Place a giant off-white paper/cardboard puzzle assembly in the center, casting soft shadows. Layout: Use 15 visible puzzle elements: 13 off-white connected puzzle pieces forming a rectangular mosaic, 1 vivid cobalt-blue puzzle piece inserted at the lower right edge, and 1 dashed-outline empty slot to the right of the blue puzzle piece. The puzzle should have physical texture, with rounded tabs and blanks, slight bevels, paper texture, seams, grime, and realistic shadows. Text content: The main typography occupies the puzzle surface. On the top row, write in a huge bold black sans-serif Chinese font; on the middle row, write . The letters should be oversized, slightly cut by the puzzle seams, and integrated into the tile layout. Keep the text clear and high-contrast. Visible graphic elements: Embed 7 small UI/chart motifs on the puzzle pieces: 1 dark code editor panel at the lower left, with brief colorful code lines and a small </> symbol; 1 pie chart combined with a small bar chart at the lower middle; 1 simple node-and-connector flowchart near the lower right center; 1 bulleted list panel with three dots to the right of the flowchart; 1 user profile card with an avatar icon and horizontal text lines at the upper right; 1 small spreadsheet/dashboard grid with gray cells and one blue highlighted cell at the upper right; 1 document/image card with a small mountain-range thumbnail line on the right, overlaid with a blue chat bubble containing two white dots and two white horizontal lines. Visual style: High-end tech editorial illustration, cinematic lighting, tactile paper puzzle texture, a soft monochromatic palette of black, warm off-white, gray, and accent cobalt blue . Add subtle scratches, dust, and paper grain. Use realistic shadows between puzzle pieces, but keep the overall image clean and readable. Constraints: No human figures, no extra logos, no watermarks, no random English characters except tiny unreadable code strokes, and no additional large blocks of text. The blue puzzle piece should feel like the key missing component that completes the system, while the dashed empty slot implies that another puzzle piece is still missing.
