React 19.2.4 — bundled with esbuild via `algernon --bundle`

React 19 removed UMD/standalone builds. These files were produced by:

  # 1. Bundle react as an IIFE that sets window.React
  algernon --bundle react-entry.js --bundle --platform=browser --format=iife \
    --global-name=React --define:process.env.NODE_ENV='"production"' \
    --minify --outfile=react.production.min.js

  # react-entry.js:
  #   var React = require('react'); module.exports = React;

  # 2. Bundle react-dom/client as an IIFE that sets window.ReactDOM,
  #    reading React from window.React via a shim (avoids duplicate instances)
  algernon --bundle node_modules/react-dom/client.js --bundle \
    --platform=browser --format=iife --global-name=ReactDOM \
    --define:process.env.NODE_ENV='"production"' \
    --alias:react=./react-global-shim.js --minify \
    --outfile=react-dom.production.min.js

  # react-global-shim.js:
  #   module.exports = window.React;
