Banner Editorial Tech com Quebra-Cabeça

An ultra-wide editorial hero banner about [Codex's next puzzle piece], featuring a tactile jigsaw-puzzle metaphor for AI software engineering and visual design. A dark charcoal technical background with faint grid lines, subtle blueprint annotations, fine dots, and thin circuit guide lines. Centered in the composition is a large off-white paper and cardboard jigsaw puzzle assembly casting soft, realistic contact shadows. Layout and elements: 15 distinct puzzle pieces arranged in a rectangular grid—13 off-white connected cardboard pieces, 1 inserted puzzle piece in vivid [cobalt blue] at the bottom-right edge, and 1 dashed-outline empty slot immediately adjacent to the right of the blue piece. The pieces feature physical rounded tabs, slight beveled edges, realistic seams, subtle paper fiber texture, and faint handling grime. Typography: Oversized, bold black sans-serif Chinese characters dominate the puzzle surface, reading "[Codex的]" across the top row and "[下一块拼图]" across the middle row. The letters are cleanly divided across puzzle piece seams while remaining crisp and legible. Embedded UI motifs: Exactly 7 miniature tech and workflow diagrams appear on individual puzzle pieces: a dark mini code editor with colored syntax and a "</>" icon in the lower left; a small hybrid pie and bar chart in the lower middle; a simple node-and-connector workflow diagram at the lower center-right; a three-item round bulleted list panel to its right; a user profile card with an avatar in the upper right; a small data spreadsheet grid in the top-right corner with one blue highlighted cell; and a document preview card overlaid by a blue chat bubble with two white dots and horizontal text lines. Lighting and style: Premium tech editorial illustration, cinematic directional lighting, tactile paper texture, muted monochrome palette of deep charcoal, warm off-white, and gray with striking [cobalt blue] accents. Clean, sharp composition with no people, no watermarks, and no extraneous text.
