Covers all major free-host platforms (github.io · vercel · netlify · pages.dev · web.app/Firebase · wordpress · neocities · surge · glitch · heroku · workers.dev · replit · weebly). With isolate-all-free-hosted ON, EVERY one opens in the VIYUH disposable browser; real domains stay silent. LIVE sites render inside the viewer; the rest still ISOLATE at navigation time (before DNS), even if they don't resolve.

Extension v0.8.7+ reloaded · keep chrome://extensions → VIYUH BDR → service worker open. POS must detect; NEG/FP must stay silent; LIVE = real-host steps.
