Project Overview

Astrolabe is a lightweight, browser-based snippet manager for Vega-Lite visualizations. Pure vanilla JavaScript, no build tools, retro Windows 2000 aesthetic.

Architecture

• Frontend-only: HTML/CSS/JavaScript with CDN dependencies (Monaco Editor, Vega-Embed)
• Storage: localStorage with Phase 0 schema (id, name, created, modified, spec, draftSpec, comment, tags, datasetRefs, meta)
• Structure: Three resizable panels (snippet library, Monaco editor, live preview)
• No build tools: Open index.html directly in browser
