Paliet looks like the most playful case, but the product problem is serious: if a user approves a generated poster, the export has to preserve that decision. A beautiful editor is not enough if the downloaded result changes geometry, labels, framing, palette, mask, or resolution.
That made output fidelity a product invariant. The work had to connect visual taste, editor state, renderer behavior, checkout, account state, export credits, and privacy rights into one trustworthy loop.
The case also shows product restraint. Physical commerce and mockup providers were explored, but not shipped as default behavior when proof-order quality, provider geometry, licensing, cost, and purchase intent were not strong enough.
