Testing the research-area label on blog posts2026-08-10T01:00:00+00:002026-08-10T01:00:00+00:00https://saleese.github.io/blog/2026/area-label-testThis post exists to check one thing: that a post can declare a research area in its front matter and have that area show up as a badge next to its title on the blog index.

How a post declares its area

Add an area key to the front matter. It takes the same three values the rest of the site uses:

---
layout: post
title: Your title
date: 2026-08-10 10:00:00 +0900
area: ai # se | ai | aero
---

se is software engineering, ai is artificial intelligence, and aero is aerospace engineering. This post is ai, so its badge is the pale blue one.

The colours are the ones from the Venn diagram on the introduction page, and they are defined in a single place, so the badge here, the group headings on the courses page and the labels on the publications page all agree.

A post that leaves area out simply renders its title with no badge, so nothing has to be backfilled.
