DESIGN.md Changed My AI Web Design Workflow

You are helping me turn one specific YouTube video into real, durable learning.

Source video:
- Title: DESIGN.md Changed My AI Web Design Workflow
- URL: https://www.youtube.com/watch?v=wRTu2dWpG4A
- Topic: Interfaces + Open Design
- My current learning frame: Pick one real landing page, import it into Ora to capture its screenshot and DESIGN.md, then transform the generated base into an original branded site by rewriting copy, swapping assets, and attaching a component reference for one refined section.
- Why this matters: New playlist item from Sourany Studio; queued for transcript-backed review, topic mapping, and a practical learning artifact.

Transcript anchors from this exact video:
- 1:26 / Evidence 1: "But instead of one picking from the small preview, I can click library to explore much more. Now, inside the library, we can see many different design MD template. This is basically a collection of reusable design system."
- 3:31 / Evidence 2: "option. We can click add to prompt to use this design system. We can also download the Design MD file to save and reuse later. And we can also download the HTML file, which is useful before it..."
- 5:47 / Evidence 3: "doesn't always have to be final. You can still refine it section by section. For example, if I want the hero to feel more premium, I can prompt improve the hero section while keeping the same design MD,..."
- 8:28 / Evidence 4: "clean typography, product interface preview, dark technical styling, smooth spacing, and a lot of small UI detail. So, instead of starting from a blank page, I can paste the website URL directly into Aura. And Aura will analyze..."
- 10:18 / Evidence 5: "prompt. It has the screenshot, has the primary visual reference, and the design MD has a secondary design system reference. And what really nice is that Aura also generate the prompt automatically. So, I don't even need to..."
- 12:43 / Evidence 6: "and make it my own. But for learning, experimenting, or creating an inspired design system, this workflow is really powerful. Now, let's try another website. This time, I'm going to test with webflow.com. The process is the same."
- 16:09 / Evidence 7: "For example, I can prompt something like this. Transform this page into an original creative agency website. Do not keep the Webflow branding, original text, or exact Change the brand name to Nova Studio, and etc. This time,..."

Your task:
1. Use the transcript anchors above as the primary source packet. If you add outside context, label it clearly as outside context and keep it secondary.
2. Create a source-check table with columns: timestamp, claim, what the demo proves, confidence, and what still needs verification.
3. Extract the actual teachable claims from the video. Do not invent claims that are not supported by the title, lesson frame, or transcript anchors.
4. Build a reusable learning artifact: A UI critique sheet for judging whether an AI interface improves control.
5. Include:
   - a plain-English definition of the core idea
   - a diagram or structured model using this sequence: Intent -> Canvas -> Artifact -> Preview -> Feedback -> Iteration
   - 3 concrete examples that apply the video idea to real agentic work
   - 2 failure modes the video helps prevent
   - a checklist I can use the next time I run Codex or Claude
   - one practical exercise with a clear done signal
6. Add a "learning transfer" section: what changes in my workflow tomorrow if I actually learned this?
7. Add a "source check" section that cites which transcript anchor supports each major takeaway.

Quality bar:
- Make this specific to "DESIGN.md Changed My AI Web Design Workflow", not a generic Interfaces + Open Design essay.
- Prefer operational examples, failure modes, and reusable artifacts over broad definitions.
- Call out uncertainty instead of smoothing over weak evidence.
- If evidence is weak, say what transcript segment or timestamp needs review instead of guessing.
- Finish with a concise artifact I could paste into my learning app.
