Tessellate is a scroll-section landing — dark fullscreen header, icon feature band, image gallery, and closing CTA. You want that shell running against real Dune content, not a static HTML5 UP unzip sitting next to it.

From JSR (recommended)

dune theme:install jsr:@dune/theme-tessellate@1.0.1 --activate

Pins an exact version in the site import map. After install, dune lockfile:sync picks up the change, so the vendored static/html5up/ CSS, section images, and webfonts ship with the package — no hand-copying files into themes/tessellate/.

From a ZIP

Grab tessellate-1.0.1.zip from dune-themes releases, extract into themes/tessellate/, then set:

# site.yaml
theme:
  name: tessellate

Either path installs the same package. Prefer JSR when you want theme updates without re-downloading ZIPs by hand.
