Paper Texture Swatch Grid

Create a 16:9 paper texture collection contact sheet showing exactly 10 rectangular paper swatches in a clean 5-column by 2-row grid, filling the entire frame edge to edge with no gaps, no borders, no labels, and no shadows. Canvas size should be canvas_size. Each swatch is a flat overhead scan-style texture with realistic matte paper grain, subtle fibers, fine speckles, and gentle uneven tonality. Top row, left to right: 1) bright minimal white paper with very fine grain, 2) warm ivory recycled paper with tiny brown flecks, 3) tan kraft paper with soft mottling and natural pulp fibers, 4) cool light gray paper with smooth fine grain, 5) off-white fibrous handmade paper with visible crisscross fibers and faint creases. Bottom row, left to right: 6) white rough watercolor paper with pronounced tooth and subtle deckle-like texture, 7) clean smooth white stationery paper with barely visible fibers, 8) pale beige parchment paper with aged speckles and warm uneven stains, 9) medium cool gray paper with cloudy mottling and soft grain, 10) deep charcoal black paper with visible fiber texture and low-contrast grain. Use natural soft lighting, high-resolution macro texture detail, realistic scanned paper surfaces, neutral color accuracy, and a minimal design suitable for texture references or design backgrounds. Avoid text, objects, hands, logos, watermarks, perspective distortion, seams beyond the grid divisions, and decorative elements.
