TOPIC-049 — test instructions

ADO bug: 21814

Was failing: Hero image alt text had no usable maxlength — over-limit saved silently.

Fix applied: #process callback appends maxlength after the image widget builds the alt box.

Tester steps:

1. Edit this node → hero image field → upload any image.
2. Type 125 chars in Alt text → accepted; char 126 is blocked.
3. Save → validation stays clean.

Expected: Alt capped at 125 in the widget.
