Review found a gap in the idempotency marker added for Task 16: if external code wraps our patched console.error between two of our own installs, the marker sees an unmarked function and treats it as virgin, capturing the external wrapper itself as "the original". That both double-records (the old patch is still reachable inside the wrapper's closure) and makes __resetConsoleErrorBuffer() restore to the wrapper instead of the real original. Fix: stash the true original exactly once, directly on the `console` object (not module scope, so it survives HMR too), and always re-wrap that stashed reference rather than whatever console.error currently is. Reinstalling after an external wrap now discards that wrapper instead of guessing whether it still chains to us -- a deliberate, documented trade-off, since there is no safe way to tell those two cases apart from the outside. Also: window error/rejection listeners now catch exceptions from a hostile e.reason the same way the console.error patch already did, and the module doc comment now notes the known HMR buffer-orphan wrinkle. Adds two tests covering the external-wrapper and module-re-execution scenarios; both were mutation-verified to fail against the prior implementation.

WHP Site Builder v2
A visual drag-and-drop website builder for WHP, rebuilt from the ground up with Craft.js, React 18, and TypeScript. Replaces the legacy GrapesJS-based editor.
Quick Start
npm install
npm run dev
Opens at http://localhost:5173. The editor runs in standalone mode without WHP integration.
Build and Deploy
# Build production bundle
npm run build
# Deploy to WHP
cp dist/index.html /docker/whp/web/site-builder/editor.html
cp -r dist/js/ /docker/whp/web/site-builder/js/
cp -r dist/css/ /docker/whp/web/site-builder/css/
The PHP wrapper (index.php) injects WHP_CONFIG (user session, CSRF token, site ID) into the HTML before serving.
Architecture
- Craft.js - React-based visual editor framework (no iframe, direct DOM rendering)
- Inline styles - All user content uses React CSSProperties, no class-based CSS
- Component pattern - Each component is a self-contained file with: render logic, settings panel, Craft.js config, and HTML export method
- 3-panel layout - Left (blocks/pages/layers/assets), Center (canvas with device preview), Right (styles/settings/head)
- Dark theme - CSS custom properties, Inter font, blue accent
