Extract ONLY the existing small foreground icon objects from the source image (do not redraw, do not beautify, do not substitute similar icons). Preserve exact original shape, stroke, color, proportions, internal cutouts, and visual identity. Place all extracted icons on a SINGLE sparse chroma-key sheet laid out in a grid with VERY generous gaps between neighboring icons and at least 80px outer padding on every side so each icon can be cleanly cropped out later.

Icons to extract (in this exact order, top-left to bottom-right, 4 columns × 5 rows):
Row 1: bar-chart-base magnifier (under 95% bar, left side), bar-chart-base sliders (under 90% bar), bar-chart-base database (under 88% bar), bar-chart-base people (under 92% bar)
Row 2: bar-chart-base shield-lock (under 85% bar), bar-chart-base link-chain (under 93% bar), radar-vertex magnifier (top vertex of radar), radar-vertex sliders (right-upper vertex)
Row 3: radar-vertex database (right-lower vertex), radar-vertex people (bottom vertex), radar-vertex shield-lock (left-lower vertex), radar-vertex link-chain (left-upper vertex)
Row 4: footer brain icon (bottom row left), footer chip icon (bottom row middle), footer rocket icon (bottom row right), small circular pillar number marker (small numbered circle "1" style)
Row 5: small circular pillar number marker "2" style, small circular pillar number marker "3" style, small circular pillar number marker "4" style, center dataflow dot icon (small glowing dot at center cross)

Use a pure bright neon green #00ff40 chroma-key background for the sheet. Do NOT include any text, labels, captions, percentages, axis numbers, or watermarks. Do NOT redraw or simplify icons. Do NOT add new icons. Output must be a single 1536x1024 PNG with all 20 icons on a sparse grid and neon green background.
