Flutter Pascal Triangle Card with Odd Entry Pattern and Row Sums
A Flutter Pascal's triangle card for maths and tutoring apps: rows 0 to 7 as binomial coefficient tiles, odd entries shaded so the Sierpinski pattern shows, and a row sum gutter doubling from 1 to 128. Counts 36 entries, 27 odd, 255 total. Centred wind_kit rows, one node per number.
