- /404[-_]error/i, /error[-_]graphic/i — Broadcom 404-ERROR-GRAPHIC.png
- /\/icon[-_]library\//i — D-Link navigation/icon-library path images
- /[-_]illustration[._]/i — Arista Cloud-Legacy_Illustration and similar diagrams
- Nokia banner, Huawei marketing, banners/ path patterns (Playwright scraper)
