open-design-v0.2.0

🎉 **`45 PRs` · `23 contributors` · `24 hours`** — Open Design 0.2.0 is here, and it's the biggest single-day product wave this project has shipped. ⚡ Generate image / video / audio inside the chat. Ship cinematic videos with 11 ready-to-go HyperFrames prompts. Build polished slide decks with the new `html-ppt` skill. Drop screenshots straight into preview comments. Toggle dark mode. Speak 13 languages. And under the hood: headless `--prod` deploy + OpenClaude fallback. **Built by the community, in a single day.** 🚀

## 🔥 Highlights

- 💬 **Click-to-comment on HTML previews — pins anchor to elements, feed straight to your agent.** Pick an element, drop a pin or screenshot; selected comments become hidden agent context, turning "make this blue" into a real revision. (#284) Thanks @alchemistklk.
- 🎬 **xAI Grok Imagine integration — image, video, and native audio in one stack.** Bring your own xAI key, generate all three media types right inside chat. (#276) Thanks @lefarcen.
- 🎞️ **11 new HyperFrames video prompt templates.** Cinematic openers, product reveals, character intros — pick a template, swap a couple of details, get a video that looks director-shot. Zero prompt engineering, zero blank canvas. (#227) Thanks @pftom.
- 🖼️ **New `html-ppt` skill for HTML slide decks.** The lewislulu/html-ppt-skill is now built in with **15 production-ready Example cards**. Idea → polished deck in minutes — no PowerPoint, no Figma file, no design tax. (#193) Thanks @pftom.
- 🌒 **Dark mode — system / light / dark toggle across the entire UI.** Settings, Chat, and Preview panes all got a fresh coat. Finally. (#259) Thanks @sysCat64.
- 🌍 **Four new UI languages: Hungarian, Polish, Korean, Turkish.** Open Design now ships with 13 UI locales out of the box — the localization community keeps showing up. (#233, #253, #273, #288) Thanks @codefl0w, @2YoungKim, @karolgajda-techsquare, and @komlosizsolt.

## ✅ System Requirements

- **macOS** — Apple Silicon (arm64) only, macOS 11 Big Sur or newer. Intel macs are not supported in 0.2.0.
- **Windows** — x64, Windows 10 / 11. Installer is **unsigned** (SmartScreen will warn on first launch — choose "More info → Run anyway").
- **Linux** — no packaged build; run from source or via the new `--prod` headless mode.
- **From source** — Node.js 24.x and pnpm 10.33.2+ (per `engines` in `package.json`).

## ⚠️ Known Issues

- 🪟 **Windows installer is unsigned** — SmartScreen / antivirus warnings on first launch. Code signing tracked for a follow-up release.
- 🍎 **No macOS Intel (x64) build** — Apple Silicon only.
- 🐧 **No Linux desktop package** — `--prod` headless mode now makes self-hosting straightforward.
- 🌐 **i18n metadata drift on new prompt templates** — A handful of recent prompt templates don't yet have display titles in every UI locale; the `release-stable` i18n coverage test is currently skipped. Tracked as a follow-up.
