- Replace firebase (32MB) with modular @firebase/app + @firebase/auth (~15MB) - Remove @iconify/json (390MB) - @iconify-json/ph (4.4MB) already covers all used icons - Replace octokit with lighter @octokit/core (only .request() method needed) - Remove unused @astrojs/starlight-tailwind and @astrojs/tailwind (using @tailwindcss/vite) - Optimize react-syntax-highlighter: use PrismLight with only needed languages + ESM imports - Add Vite manual chunks for Firebase and React vendor splitting
…ighlighting Replace the move->rust fallback with a proper Move language grammar that handles Move 2.x syntax: modules, structs, enums, abilities, address literals, annotations, and common control flow keywords.
- Convert Firebase app and auth initialization to async with dynamic imports. The vendor-firebase chunk (~155KB) is now only fetched when a user interacts with auth (Faucet page), not eagerly on every page. - Lazy-load ChatMessage via React.lazy() so react-markdown, react-syntax-highlighter, remark-gfm, and Prism language grammars are deferred until chat messages are actually rendered. - Both changes reduce the initial page load for the vast majority of users who never use the Faucet or the chat widget.

Optimize dependencies and build configuration to significantly reduce bundle size and improve caching.
Dependency Optimizations
@iconify/json(~390MB): The full icon set was in dependencies but only theph(Phosphor) set is used.@iconify-json/ph(~4.4MB) was already in devDependencies.firebasewith@firebase/app+@firebase/auth: Only Firebase App and Auth were used. Switching to modular packages reduces the dependency tree by ~17MB.octokitwith@octokit/core: Only.request()was used (for rate limit checks). The fulloctokitSDK bundles many unused plugins.@astrojs/tailwind: Unused Astro integration — the project uses Tailwind v4 directly via@tailwindcss/vite.Build Optimizations
react-syntax-highlighterPrismLight: Switched fromPrism(loads all ~300 languages) toPrismLightwith 12 specifically registered languages (bash, go, javascript, json, move, python, rust, solidity, toml, tsx, typescript, yaml), dramatically reducing the chat widget bundle.prism-move.ts— a refractor-compatible Prism grammar for Move 2.x syntax (modules, structs, enums, abilities, address literals, annotations, control flow). Replaces the previousmove → rustfallback in the chat widget.manualChunksto split Firebase and React vendor code into separate, independently-cacheable chunks.Dynamic Loading
