## Description

Poly-Filter automatically scans product pages for synthetic materials like polyester, nylon, spandex, and acrylic then flags products so you can shop for natural fibers with confidence. No more squinting at fabric labels buried in product descriptions.

How it works:
When you browse a retail site, Poly-Filter scans product pages in the background and dims any items containing synthetic materials in the gallery grid. A small badge shows exactly which synthetics were found. On individual product pages, a banner alerts you right away.

Works across a wide range of retail sites including American Eagle, Disturbia, Aritzia, BlackMilk, and most Shopify-powered stores. The extension runs entirely in your browser — no data is collected or sent anywhere.

Features:
- Detects 17+ synthetic materials including polyester, nylon, spandex, elastane, rayon, acrylic, PVC, faux leather, and more
- Dims flagged products in gallery grids with a hover-to-reveal option
- Scans product pages using fabric descriptions, structured data, and metadata
- Toggle individual materials on or off from the popup
- Persistent cache so previously scanned products load instantly
- Parallel scanning for fast results on large product listings
- Lightweight status pill shows scan progress in real time
- Completely private — everything runs locally, zero data collection

Perfect for anyone who wants to avoid fast fashion synthetics, shop sustainably, or simply prefers natural fabrics like cotton, wool, linen, and silk.
