How Systems Think
This is the first Article — a placeholder that proves the IA.
Articles are long-form, evergreen essays. They live under /articles/ with clean URLs like /articles/how-systems-think/, emit Article (not BlogPosting) JSON-LD, and are surfaced separately from the dated log at /blog/.
The blog remains a journal — 340+ posts, chronological. Articles are fewer, deeper, canonical. When an existing post graduates (e.g. mental-models, rules-of-debugging), move its file from content/blog/ to content/articles/ and leave an aliases: [/blog/old-slug/] so old links 301.
Edit this file or replace it. Delete it once the first real Article lands — the section
_index.mdkeeps/articles/visible even when empty.
