M-5 made safeUrl() block data:image/svg+xml everywhere, including the image-only sinks (<img src>, CSS url()) that Gallery's default images and other SVG placeholders rely on. Loaded as an image, an SVG is rasterized and never executes an inline <script>/onload= -- that only happens when it's navigated to or loaded as an <iframe> document -- so M-5 over-blocked the safe contexts and broke every published Gallery (and other components using an SVG placeholder) using safeUrl's default images in prod. Adds safeImageUrl(): identical javascript:/vbscript: handling to safeUrl, but treats data: as an allowlist of image/* subtypes instead of a blocklist -- allows all data:image/* (including svg+xml, with or without base64), still blocks data:text/html and any other non-image data: type. Swapped to safeImageUrl at IMAGE-src / CSS-image url() sinks only: - Gallery.tsx img src + lightbox data-lb-src - ImageBlock.tsx img src (toHtml) - Logo.tsx / Navbar.tsx logo <img> src (their href/link targets keep safeUrl) - style-helpers.ts sanitizeCssValue's url(...) handling (background-image for HeroSimple/BackgroundSection/Section/CallToAction) Left on safeUrl (href/iframe/form-action/navigation sinks, where data:image/svg+xml must stay blocked): ButtonLink, Icon link, SocialLinks, Menu/Navbar link hrefs, PricingTable buttonHref, _cta-helpers, ContentSlider buttonHref, FeaturesGrid buttonUrl, FormContainer action (via form-relay-wiring), MapEmbed/VideoBlock iframe src.

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
