refactor: rename content types to semantic taxonomy
- vault → notes (PKM-exported content)
- posts → articles (short-form, no TOC)
- papers → essays (long-form, with TOC)
- type: post → type: article (posts are just short articles)
- layouts/paper → layouts/essay
- 08a-paper.css → 08a-essay.css
- CSS: fix redundant li resets, remove role="main" from article,
  replace <small> prev/next labels, add console layout
- Update hugo.toml menus, internal URLs, front matter throughout
- Add docs/context.md, docs/css-refactor-plan.md

Overview

Use data-diff on a <pre> block to render a structured diff. Child elements carry line-level semantics.

<pre data-diff>
  <span data-line="hunk">@@ -12,7 +12,9 @@</span>
  <span data-line="context"> function greet(name) {</span>
  <span data-line="removed">-  return "Hello " + name;</span>
  <span data-line="added">+  const greeting = `Hello, ${name}!`;</span>
  <span data-line="added">+  return greeting;</span>
  <span data-line="context"> }</span>
</pre>

Line Types

Value Meaning
hunk Hunk header (@@ ... @@) — muted, italic
context Unchanged surrounding line — default text
removed Deleted line — red background, - prefix
added New line — green background, + prefix

Inline Diffs

For single-value changes in prose, use data-diff directly on <del> and <ins>:

<p>
  Latency changed from
  <del data-diff="removed">240ms</del>
  to
  <ins data-diff="added">18ms</ins>
  after the index rebuild.
</p>

Notes

The data-diff block expects monospace rendering. ASW applies font-family: var(--asw-font-mono) automatically — no additional class needed.
