🎨 Palette: Improve ImageUploader accessibility#45
Conversation
- Added `tabIndex={-1}` and `aria-hidden="true"` to the visually hidden file input to properly exclude it from the accessibility tree.
- Added `focus-visible` styling (`focus-visible:ring-blue-500`) to the "Select File" button.
- Added an explicit `aria-label` (using translations) to the "Remove Image" icon-only button, included `aria-hidden="true"` on the internal icon, and added a red `focus-visible` ring.

Code Review
This pull request introduces accessibility enhancements to the ImageUploader component, such as adding focus-visible ring styles, hiding the native file input from screen readers using tabIndex={-1} and aria-hidden="true", and adding an aria-label to the remove button. These learnings are also documented in .Jules/palette.md. The review feedback recommends explicitly setting type="button" on both the "select file" and "remove image" buttons to prevent accidental form submissions if the component is used inside a form.

The button element is missing an explicit type attribute. In HTML and React, buttons default to type="submit" when placed inside a form, which can cause unexpected form submissions if this component is ever rendered within a form context. It is a best practice to explicitly set type="button" for non-submitting buttons.

Similar to the select file button, this destructive "Remove Image" button is missing an explicit type attribute. Explicitly setting type="button" prevents accidental form submissions if the ImageUploader is used inside a form.

💡 What: Improved the keyboard navigation and screen reader accessibility for the
ImageUploadercomponent. Added a visually distinct focus ring for both the primary "Select File" button and the destructive "Remove Image" overlay button. The native hidden file input was also explicitly removed from the accessibility tree, and the icon-only "Remove Image" button received proper ARIA labeling.🎯 Why: To make the component fully usable and understandable via keyboard navigation and screen readers. Users relying on keyboard navigation can now clearly see which element is focused, and screen reader users will receive proper context instead of encountering confusing hidden inputs or unlabelled icon buttons.
♿ Accessibility:
className="hidden") now hastabIndex={-1}andaria-hidden="true"to prevent it from trapping focus or being announced improperly.aria-label={t('removeImage')}for screen readers, sets the internal<X />icon toaria-hidden="true", and utilizes a red focus ring (matched to its destructive action) combined withshadow-lgto prevent clipping within itsoverflow-hiddencontainer.A new entry was also added to
.Jules/palette.mdto document the learnings around handling focus rings for absolute positioned overlay buttons.PR created automatically by Jules for task 5820012902974999884 started by @MacTechIN
Note
Low Risk
Small presentational and ARIA-only changes in one UI component; no auth, data, or API impact.
Overview
Improves keyboard and screen reader behavior in
ImageUploaderwithout changing upload logic.The hidden file
<input>is removed from the tab order and accessibility tree viatabIndex={-1}andaria-hidden="true". The Select File trigger gets visiblefocus-visiblering styling. The overlay Remove control getsaria-label, the icon is markedaria-hidden, and a redfocus-visiblering (with offset) so focus stays visible inside theoverflow-hiddenpreview.Documents the pattern in
