Installing Dimension
Dimension’s home is a centered header with a gem logo and a short nav.
Clicking a nav item reveals an article panel over the landing — not a
full page reload in the upstream HTML. On Dune, those nav items are real
routes; the panel chrome still opens with is-article-visible.
From JSR (recommended)
dune theme:install jsr:@dune/theme-dimension@1.0.1 --activate
From a ZIP
Extract dimension-1.0.1.zip into themes/dimension/ and set
theme.name: dimension.
Open / first — you should see only the landing. Then open Blog or About
and confirm the article panel appears with a close control and Escape
support. Prefer JSR for versioned updates.
