- Added aria-label to the remove image icon-only button - Added aria-hidden="true" to the X icon inside the remove button - Implemented focus-visible outline/ring utility classes on both the "Select File" and "Remove Image" buttons - Used offset rings and appropriate ring colors (red for remove) to ensure visibility inside the overflow-hidden container - Added `.Jules/palette.md` to document accessibility learning on focus rings for absolutely positioned elements inside overflow-hidden containers Co-authored-by: MacTechIN <63564804+MacTechIN@users.noreply.github.com>

Code Review
This pull request improves keyboard accessibility and ARIA attributes for interactive elements in the ImageUploader component, and adds a corresponding learning entry to the documentation in .Jules/palette.md. Feedback on the documentation notes that it contains literal backslash-n characters instead of actual newlines, and incorrectly describes the button as being inside an overflow-hidden container when it is actually a sibling.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

| ## 2024-03-20 - [Accessibility] Handling focus rings on absolute positioned elements in overflow-hidden containers\n**Learning:** When placing absolute positioned interactive elements (like an overlay close button) inside a container with `overflow-hidden`, standard focus rings can get clipped, making them invisible or partially hidden, which harms keyboard accessibility.\n**Action:** Use `focus-visible:ring-2 focus-visible:ring-offset-2 focus-visible:outline-none` combined with `shadow-lg` to ensure the focus ring respects offsets and is visible. Additionally, adjust the focus ring color to match the intent of the action (e.g., `focus-visible:ring-red-500` for a destructive remove action). | |||

There are two issues with this documentation entry:\n\n1. Literal backslash-n characters: The text contains literal backslash-n characters instead of actual newlines, which prevents Markdown parsers from rendering it as separate paragraphs.\n2. Inaccurate technical context: The learning states that the button is placed inside a container with overflow-hidden. However, in src/components/ImageUploader.tsx, the button is actually a sibling of the overflow-hidden container (the wrapper for the image) and is a direct child of the relative container (which does not have overflow-hidden). Therefore, the focus ring was never at risk of being clipped by overflow-hidden in this specific layout.\n\nPlease update the file to use actual newlines and correct the technical description.

💡 What
Added proper keyboard focus states (
focus-visibleclasses) to the buttons in theImageUploadercomponent and explicitly added anaria-labelto the "Remove Image" icon-only button. Also documented a critical accessibility learning regarding focus states on absolute positioned elements within overflow-hidden containers in.Jules/palette.md.🎯 Why
Keyboard navigation users previously could not easily discern when the "Select File" or "Remove Image" buttons were focused. Additionally, screen reader users lacked explicit context for the "Remove Image" button since it only contained an icon without an ARIA label.
📸 Before/After
(Visual changes only apply to the focus state when using keyboard navigation. The standard UI remains identical.)
Before: Tabbing to the buttons provided no explicit visual feedback (no focus ring).
After: Tabbing to the buttons now highlights them with an accessible outline ring. The "Remove Image" button explicitly uses a red ring to signify its destructive nature, offset to prevent clipping by the container bounds.
♿ Accessibility
