+# trending-dw — Trending Bestseller Intelligence
+
+`trending.designerwallcoverings.com` — an Amazon-style dashboard of what's selling across
+Google data points and print-on-demand marketplaces (Spoonflower, Etsy, Society6, Creative
+Market, William Morris et al): **which company, which item, which marketplace, and its
+bestseller signal**.
+
+## Run
+```
+npm start # http://127.0.0.1:9948 (basic-auth admin:DW2024!)
+npm run seed # rebuild data/bestsellers.json from research
+```
+
+## Layout
+- **Left panel (Amazon-style facets):** Marketplace · Company · Style · Color · Price, with live counts + click-to-filter.
+- **Top bar:** result count · Sort (Bestseller signal / Newest / Title / Company / Marketplace) · Density slider.
+- **Grid:** "new"-style cards (swatch tile from dominant color, NEW ribbon, signal rank), infinite-scroll.
+- All three DW hard-rule grid controls present: **sort + density + infinite scroll**.
+
+## Data
+`data/bestsellers.json` is generated by `scripts/seed.js` from the 2026-07-02 design-trend-scout
+Exa research. To keep it live, re-run design-trend-scout on a schedule and regenerate the seed
+(the refresh feed is the intended next wiring — see below).
+
+## Gated switches (Steve flips)
+- **Public go-live:** set `BASIC_AUTH=''` to remove the auth gate (default is gated — it publishes competitor intelligence).
+- **DNS:** `trending` CNAME/A on Cloudflare → Kamatera `45.61.58.125`.
+- **Deploy:** `/deploy` to Kamatera (pm2 `trending-dw`).
+- **Live Google/POD feed:** wire `scripts/seed.js` to the design-trend-scout Exa pipeline for scheduled refresh (metered — show cost).
+
+## Notes
+- **No copyrighted marketplace images** are stored/served — cards render color-swatch tiles. This is intentional (copyright + it's a public DW subdomain).
