Image numbers on Adafruit CDN aren't contiguous — scrape all
available image URLs from the product page gallery instead of
iterating through a hardcoded range.

 2. **CRITICAL — Always use the `/original/` CDN URL, NOT `970x728` or `640x480`.**
    The Adafruit CDN URL contains a resolution prefix. You MUST replace it with `original`
    to get the highest-resolution source for downscaling. Downloading a pre-scaled version
    (e.g. `970x728`) produces a blurry 400x300 result.
