What this is

A static site built with Astro for publishing research notes and project writing.

Current editorial focus:

• Unicode identifier security, confusable detection, and related open-source tooling
• Applied AI systems in legal and product contexts
• Launch posts and technical write-ups for projects such as namespace-guard and confusable-vision

Tech stack

• Astro 5 — static site generator
• MDX — markdown with component support
• Shiki — syntax highlighting (Material Palenight theme)
• GitHub Pages — hosting
• GitHub Actions — automated deployment on push to main

Local development

npm install
npm run dev

Dev server runs at http://localhost:4321 with hot reload.

Writing a new post

Create a new .mdx file in src/content/posts/:

---
title: "Your post title"
description: "Brief description for meta tags"
date: "2026-02-20"
tags: ["tag1", "tag2"]
---

Your content here.

The post will be available at /posts/your-filename/.

To keep a post out of production builds, add:

draft: true

Deployment

Automatic via GitHub Actions:

1. Push to main
2. Workflow builds the site (npm run build)
3. Deploys dist/ to GitHub Pages

Manual build:

npm run build    # Outputs to dist/
npm run preview  # Preview the production build

Design principles

• Content-first - static HTML for posts, lightweight progressive enhancement for convenience features
• Clean typography — Syne (display), Instrument Sans (body), Google Sans Code (mono)
• Editorial presentation — structured like a research archive rather than a reverse-chronological diary
• Theme toggle — dark and light themes with local preference persistence
• Accessible — semantic HTML, skip links, focus states, ARIA where needed
• Fast — static HTML, no client-side hydration, aggressive caching
