What changed

• Add a responsive, self-contained visual lab for three cold storage shares and their site, infrastructure, and custodian dependencies.
• Show every declared single-domain loss, the surviving share indices, and whether a two-share path remains.
• Include separate, shared site, shared platform, and shared custodian presets; export a placement manifest for the full cryptographic assessment.
• Link the lab from the main page, README, and operator guide. Keep the planning-only boundary prominent and upload no files.

Verification

• node --test test/resilience-lab.test.js test/evidence-placement.test.js

The browser tool simulates topology only; it never verifies share bytes or physical placement.
