Upstream Striped is a two-column blog: a sticky sidebar (title, tagline, nav, search, recent posts, credit) and a main column of dated entries. On narrow viewports the #titleBar control opens that same sidebar as a drawer — open it on mobile when you dogfood this demo; if the toggle does nothing, the fidelity pass failed.

Dune maps the chrome to real routes instead of static HTML files:

• Home / Blog / About / Search / Archives from demo fixtures and theme posts
• Search hits /api/search (server-side), not a client Fuse index
• Contact-style forms from the HTML5 UP demo are not wired to a backend

Compare side-by-side with html5up.net/striped: coral accents, date badges, and the recent-posts list should feel like the same family. The visible “Design: HTML5 UP” link is required under CC BY when show_html5up_credit is on — don’t treat fidelity as license to strip it.
