## Agent guidance (Form Atlas editorial)
Treat each site result as a lead; open its source and license before copying code or assuming free access.

## Verification boundary
This is a source-level research record, not an item-level audit. Registry counts may include examples, variants and paid content. Inspect the exact upstream files, license, dependencies and framework version before installation. No upstream code is mirrored here. The visual on Form Atlas is an original illustrative sample, not an upstream screenshot.
