Series: First of 10 patches porting the radicle.dev visual design onto radicle.xyz. This patch lands the foundation; patches 2–10 migrate one page each (faq, legal, docs, work, history, download, guides index, guides stacked, home). They share no files, so they can be reviewed independently and merged in any order once this lands.
Purely additive — 14 new files, zero modifications to existing code.
The site renders unchanged everywhere except /preview/, a demo page
included here specifically for review.
Adds:
_layouts/app.html,_layouts/app-prose.html_includes/app/{topbar,sidebar,footer}.htmlassets/css/{app,app-colors,app-typography}.cssassets/fonts/Booton-{Regular,Medium,SemiBold}.woff2assets/js/{app-menu,code-copy}.js_pages/preview.md
Review: make serve and visit http://localhost:3000/preview/
Out of scope: Blog migration (20 posts), and removal of the now-orphaned
guide.html/index.html/page.html layouts + guide.css — that cleanup
is a separate follow-up patch once the migrations have all landed.
