Printable product generators for Etsy

Generators that build printable digital products for Etsy and check them before they ship. They produce 100 Sudoku puzzles in graded levels, each solved by code to prove a single solution, nonograms that are verified line-solvable, a kids Christmas escape room where every puzzle code is asserted to spell the final word, murder mystery case files with logic clues, colour-by-number math pictures whose sums are auto-checked, plus party games, planners and kids activity packs. Each product also gets hero mockups, preview pages, a what's-included panel and bundle collages, and is created, uploaded and activated through the Etsy API. Ideas came from scraped marketplace data scored by demand and competition. Output so far is 60+ digital products.
