minimalist cartoon illustration where each letter of the word "AI" is represented only by an outline. Inside these outlined letters, populate with tiny [lock] silhouettes spaced each other, ensuring each [lock] is confined within the outlines of the letters and does not spill outside. The lock silhouettes should be simple in design, distinct from one another, and fill up the space within each letter's outline effectively. Use [blue] color scheme. --ar 16:9
