# TileDown 0.4.1 ships static code color

TileDown 0.4.1 is about making static pages more legible without changing the
core bargain: build once, ship files.

## Static syntax highlighting

Fenced code blocks now render through a lexical highlighter during the build.
The output is ordinary HTML spans styled by the shared `styles.css`; there is no
Prism, Highlight.js, or other runtime highlighter on the reader path.

```swift
struct BuildStatus {
    let version = "0.4.1"
    let staticHighlighting = true
    let runtimeHighlighter = false
}
```

```json
{
  "languages": 19,
  "runtime": false,
  "checkedByPlaywright": true
}
```

```bash
swift run tiledown build-site content/ dist/
swift run tiledown doctor --publish content/
```

The supported language profiles cover Bash, C, C++, C#, CSS, Go, HTML, Java,
JavaScript, JSON, Kotlin, Python, Ruby, Rust, SQL, Swift, TypeScript, XML, and
YAML. Unsupported fences still render as escaped code, so authoring remains safe.

## Tags got safer

Generated tag pages now keep the tag landing page out of the top navigation
unless the site authors it there, and the Clear chip returns to the all-articles
tag page. Clearing a tag should show every article again, not an empty archive.

## The example grew teeth

The everything example now includes a Source Code page that exercises all
supported language profiles. The browser checks assert that token spans are
present and styled, so this feature is covered as generated site behavior, not
just as a renderer unit test.

This public site carries the same expectation: source blocks are colored at build
time, tag clearing is checked through browser navigation, and the WebAssembly
playground pages remain static assets copied through the website build.

TileDown 0.4.1 is available from the
[GitHub release](https://github.com/TileDown/tile-down/releases/tag/v0.4.1).
