Arcanum Site Kit (ASK) v1.2 — partials/header.html (Jinja2 include)
For FastAPI+Jinja stacks: leontief, methodex, gerhard, lewis, volcker, leonid,
freenic, shaikh.
Vendoring: copy arcanum.css + arcanum-chrome.js + ecosystem.json into the
site's static dir (served at /static/_shared/). Then in base.html
:
(2-line accent override)
...and where the header belongs (top of
):
{% include "_shared/header.html" %}
...and the chrome enhancer just before (see footer.html).
Expected template variables (all optional except site_title; provide via a
context processor so every route has them):
site_key str ecosystem.json site.key (e.g. "volcker") -> switcher "current"
site_title str display name shown next to the brand (e.g. "Volcker")
site_home str url/path the site title links to (default "/")
hub_url str default "https://heterodata.org"
nav list [{label, href, active(bool)}] blueprint vocabulary
ecosystem dict parsed ecosystem.json (for the no-JS switcher) — recommended
