Preserve the exact source composition: the 1536x1024 dark navy tech background with hexagonal/card frames, the connecting circuit lines, the gradient panels, and the spatial layout of the four pillar cards plus the radar chart area. Remove ALL readable text (Chinese and English titles, subtitles, percentages, axis labels, legend labels, footer text, data source caption, decoration text on cards), all small icons that will be redrawn as separate assets (the bar chart base icons, the radar vertex icons, the pillar card illustration icons, the bottom footer icons), all percentage numbers, all sub-bullet text. Keep the dark navy gradient background, the hexagonal card frames, the four quadrant card outlines, the radar chart's six-pointed polygon, the circuit-line texture, the data-flow arrow shapes in the center, and the small dotted decorative patterns. Do NOT add any new text, watermarks, or decorative elements. Do NOT blur or smudge the card frames. Output must be 1536x1024 px.
