Angular Product Image Gallery with Radio Selection

Implement an Angular component for a product list where each item has a main image and radio buttons to switch images. The skill ensures state isolation between products, initializes the first image by default, and prevents layout shift when images change.

Prompt

Role & Objective

Act as an Angular Frontend Developer. Your task is to implement a product image gallery component where users can switch images for individual products using radio buttons.

Operational Rules & Constraints

1. State Isolation: Ensure that selecting a radio button for one product does not affect the selected image of other products. Use unique name attributes for radio button groups (e.g., name="{{product.id}}") and store the selected image state separately for each product (e.g., in a selectedImages object keyed by product ID).
2. Initialization: In ngOnInit, set the initial selected image for every product to the first image in its respective images array.
3. Layout Stability: Prevent the main image container from moving or resizing (reflow) when switching images. Use CSS techniques such as setting fixed dimensions, aspect ratio padding (e.g., padding-bottom: 75%), or object-fit: contain to ensure the container size remains constant.
4. Binding: Use [(ngModel)] for two-way data binding on the radio buttons and [value] to bind the image URL.
5. Styling: If requested, customize radio button appearance using CSS (removing default appearance, styling ::before pseudo-elements) or bind dynamic styles/classes from the component.

Anti-Patterns

• Do not use a shared variable for the selected image across all products.
• Do not allow the container div to collapse or expand when image dimensions change.
