The build step was failing with: Error: error:0308010C:digital envelope routines::unsupported This occurs when webpack 4 (used by Docusaurus 2.0.0-beta.6) tries to use MD4 hashing with Node.js 18's OpenSSL 3, which dropped support for legacy algorithms. Setting NODE_OPTIONS=--openssl-legacy-provider in the build and deploy steps restores compatibility with the legacy OpenSSL provider needed by webpack 4.

The "Build and Deploy" CI job was failing because Docusaurus 2.0.0-beta.6 (which bundles webpack 4) uses MD4 hashing — an algorithm dropped from Node.js 18's OpenSSL 3.
Changes
.github/workflows/deploy.yml: AddedNODE_OPTIONS: --openssl-legacy-providerto both theBuild documentationandDeploy to GitHub Pagessteps, which both invoke webpack under the hood.The long-term fix is upgrading to Docusaurus v2 stable / v3 (webpack 5, OpenSSL 3-compatible hashing); this PR unblocks CI with minimal blast radius.
