Kestrel Optics — Performance Eyewear
A lens lab re-tints the visor in the photo across five lenses, and the same tints drive a live transmission chart.

Questions about Kestrel Optics
Who is Kestrel Optics for?
Kestrel Optics is for online shops and product brands and fashion labels, and for the designers, developers and agencies who build their sites. It's a foundation rather than a site for one business: ask your AI to make it about yours and it rewrites the copy, colours and images around the same build.
What is Kestrel Optics built with?
Kestrel Optics is built with HTML/CSS/JS. The source is a single HTML file: open it in a browser and it runs, with no build step. The prompt is written for coding agents such as Claude Code, Cursor and Antigravity.
Can I use Kestrel Optics for a client project?
Yes. Every purchase includes a commercial licence: use it in your own projects and in work you deliver to clients, including paid client work, change and rebrand it, and publish the result with no credit needed. What you can't do is resell, share or republish the prompt or the source files themselves.
Should I buy the prompt or the source?
The prompt is the written brief that built the design: paste it into a coding agent such as Claude Code, Cursor or Antigravity and it builds the site on your computer, which you then refine. The source is the finished project itself, ready to run exactly as the preview shows. The source always includes the prompt.
Will the prompt give me exactly the preview?
Not exactly, and that's expected. A prompt is a starting point: AI output varies between tools and between runs, so plan to refine spacing, timing and copy. The source pack is the preview itself, finished and running.
Can I get a refund?
Single designs are final once delivered, unless something is wrong on our side: a broken or empty download, a pack that isn't what its page describes, or a double charge. Then email support@brandmotion.in with your receipt and we fix it or refund it. The full terms are on the refunds page.
