What websites actually load: measured, not claimed.

We open 98 real sites in a controlled browser and record every request, cookie, and tracker, then run each through Brave’s own ad-block engine (the open-source adblock-rust, with Brave’s default lists) to show what Brave Shields, the ad and tracker blocker built into the Brave browser, would block. Reproducible evidence, not a score.
