Fake-Fast Lite

Sniffs edge-cache lipstick on a slow origin.
Not a lab suite—just fast receipts you can quote.

What it checks

• TTFB (approx.): streamed first-byte timing (ms).
• Edge/CDN hints: cf-cache-status, via, x-cache, server-timing, etc.
• Caching: cache-control, age, etag, last-modified, vary, expires.
• DOM weight tells: <script> count (inline vs external), stylesheet count.
• Heuristic verdict: “Looks Clean / Borderline / Likely Fake-Fast” + score (0–100).

⚠️ This is a lightweight heuristic. It won’t replace a proper lab test (WebPageTest, Lighthouse). It’s for fast triage and public-facing receipts.

Why this exists

“Fast” homepages that feel slow as soon as you click anything? That’s edge-cache cosplay: CDN HITs masking a sluggish origin and script buffet. This tool gives you a quick smell test.

How it works (short)

• Streams a GET and stops at first non-empty chunk for TTFB.
• Collects headers and scans HTML to count scripts and stylesheets.
• Aggregates into a score and plain-English verdict.

Limits

• Some sites block HEAD/GET or require JS to render.
• TTFB is best-effort; networks vary. Use multiple runs.
• No JS execution; this is an HTML/headers sniff.
