Structured like Matt Godbolt's newer talks (hrt-theme.css in what-happens-beneath-accu-2026): reveal.js with no stock theme but a custom dark one, every slide on a rounded panel, IBM Plex Sans and Mono, monokai code with glowing stepped lines, 16:9 with fade transitions, and the content in one Markdown file per section. Made our own: the palette is a handful of variables (with ?accent= presets for comparing), and his ring-and-thread corner motif became a chain of nodes and links, an AS path, which also opens the title slide. A wordmark sits where his decks carry the employer logo. Also: a small `bird` syntax highlighter for router config on slides, a bytes component in the four groups of the /statusz bytes view, columns, boxes, and a `bare` slide class. reveal.js 6 loads from a vendored copy when slides/vendor-reveal.sh has been run (works offline, ignored by git) and from the CDN otherwise. Section files carry a starter outline for the lab that doubles as a tour of the slide types. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

<title>BGP hands-on: announce your own prefix</title>
|
|
<!--
|
|
Deck structure and look follow Matt Godbolt's newer talks (e.g.
|
|
github.com/mattgodbolt/what-happens-beneath-accu-2026): reveal.js with
|
|
no stock theme, a custom dark theme (theme.css), monokai code blocks,
|
|
16:9, fade transitions, and one Markdown file per section.
|
|
|
|
reveal.js is loaded from ./reveal.js/dist if present (run
|
|
./vendor-reveal.sh once; works offline), otherwise from the CDN. Its
|
|
stylesheets are inserted BEFORE ours by the loader below, so theme.css
|
|
and style.css always have the last word.
