Create a finished vertical children’s number-chart poster, 2:3 ratio, on a warm matte ivory paper field with a generous cobalt-blue border. Exact headline at top: "COUNT TO 20". Below, arrange the exact number strings "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" "13" "14" "15" "16" "17" "18" "19" "20" in a precise 4-column by 5-row grid, each number centered in its own rounded-square tile. Make every numeral a custom thick display character sculpted from translucent jewel-tone optical glass: cycle ruby, sapphire, emerald, amber, violet, cyan; deep intrinsic color through each letterform, 12mm apparent thickness, softly beveled faces, crisp white specular streaks, saturated inner transmitted-light glow, visible colored refracted edges. Typography must remain extremely legible; use broad rounded proportions, open counters, uniform baseline and equal spacing. Each tile is a shallow off-white frosted acrylic plaque with a hairline cobalt outline; the glass numeral casts a small colored caustic pool and soft shadow onto its plaque. Headline is custom cobalt-blue hand-cut block lettering, flat ink with slight debossed paper texture, wide tracking. At bottom set exact supporting line: "ONE • TWO • THREE • COUNT WITH ME" in compact cobalt-blue uppercase. Bright overhead softbox lighting, clean frontal view, photographed as premium educational wall art, sharp print texture, no extra words, no misspelled text, no icons, no characters.
