// ImagePicker – public interface contracts
|
||
//
|
||
// The ImagePicker's job: present a hidden file input + a trigger button.
|
||
// We test the *behavioral contracts* derived from its props, not DOM details.
|
||
//
|
||
// Key change: multi-image support. The picker now:
|
||
// 1. Accepts a `multiple` prop that should propagate to the <input>.
|
||
// 2. Calls `onFilesSelect(files: File[])` (plural) — the whole FileList.
|
||
// 3. Deduplication is the *caller's* responsibility (page.tsx handles it).
