Layout: exactly SIXTEEN distinct icons, one in each cell of a strict 4-column by 4-row square sheet. Read left to right across each row from top to bottom. Equal square cells with no visible grid. Center each complete icon in its own cell; keep its full silhouette within the central 65 percent of that cell, leaving generous transparent separation on every side. Same optical size and visual weight throughout. No overlaps, clipped shapes, empty cells, duplicate objects or bonus decorations. Background: genuinely transparent alpha everywhere outside the icons. No white matte, checkerboard pattern, colored tile backgrounds, circles, pedestals, cast shadows, floor, border, words, letters, labels, numerals, logos or watermark. Render only this icon collection, not a UI screen, photograph or presentation mockup. Output one square PNG sheet.
