Built the responsive NIGHTWATCH site with the $9 buy links, FAQ, local assets, and complete dist/ export.

Build and typecheck passed, along with 13 interaction groups and 16/16 design checks. Delivery size: 878,077 bytes.

Setup and design are documented in README.md and DESIGN.md; full results are in artifacts/validation.md.

Limitations: the supplied checkout returned HTTP 402. Safari and payment completion remain unverified.

The site is in good shape: it meets every requirement in the brief, all 16 probe checks pass, and the product and its buy button are on the first phone screen. I found one real bug: at phone widths the FAQ heading reads "Before youget building." Nothing is high, so nothing reopens the build. The six findings are in .imd-findings.json and I changed no other files.

Requirements

• "one-page site": met. A single index.html that scrolls through hero, steps, audience, FAQ and footer.
• "the promise (Teach beginners … without writing code.)": met. The line under the headline at index.html:37 and the three steps in #inside.
• "who it is for": met. The paragraph and checklist in .audience-copy at index.html:89-94 (finding 3 is about its heading).
• "the products with prices": met. "NIGHTWATCH Checker" with "$9.00" in #product at index.html:39-46.
• "a buy button per product": met. .buy-button links to the exact URL from the brief, with a second link at index.html:95. No wallet code.
• "a short FAQ": met. Four <details name="faq"> entries at index.html:106-121.
• "Static site, fast, works on a phone": met. A Vite static export with one local font and no network requests. There's no sideways scrolling at 320, 390 or 1440. Hosting comes after review.
• The buy link answers with an HTTP 402 payment-required response, which takes payment as the brief says. That's the seller's checkout, so it isn't a finding.

The idea: a calm, book-like sales page for a $9 playbook, carried by one device, the orange crescent moon (logo, cover, accent) on night-ink and paper colours. The arrow-and-rule caption is the one thing that competes with it.

Findings

1. Medium, bug: "Before youget building." at 320 and 390 (index.html:102). The heading has no space before its <br>, and src/styles.css:187 hides that break on phones, so the two words join. I measured this in Chromium at both widths. Fix: add a space before <br />.
2. Medium, copy: the product subtitle "The guide from idea to first sale." repeats the headline right above it (index.html:41). Replace it with "Three steps: pick the idea, build it with NIGHTSHIFT, launch it."
3. Medium, copy: the audience heading "Big idea. After-hours energy." never names the audience (index.html:86). Change it to "For side-hustlers / and indie builders." It's also one of six slogan-style lines on the page.
4. Low, taste: the caption under the cover, "A little direction goes a long way.", has an arrow and underline like a link but goes nowhere (index.html:52). Delete it; the cover stays centred.
5. Low, fidelity: the page calls the Checker only a "digital guide" (index.html:108). The brief's buy link describes it as a browser checker tool ("paste in your work and see exactly what to fix"). I kept this low because the brief itself says "guide". The replacement wording is in the findings file.
6. Low, copy: the page title and og:title contain an em dash (index.html:7, index.html:10). Change both to "NIGHTWATCH: from side idea to first sale".

Limits: this machine has no WebKit browser, so I only checked the page in Chromium and couldn't test Safari. The page uses no CSS that WebKit lacks: <details name> needs Safari 17.2 or later, and older Safari just lets more than one FAQ answer stay open.

The probe's screenshots in test/scratch are deleted.
