# 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.
