Astral is a portfolio shell: icon navigation, an intro panel with a portrait jumplink, and additional panels for projects and links. On Dune those panels deep-link to real routes instead of static HTML fragments from the upstream zip.

From JSR (recommended)

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

Pins the package in the import map; dune lockfile:sync afterward.

From a ZIP

Extract astral-1.0.1.zip into themes/astral/ and set theme.name: astral.

Visit / for the intro panel and /blog for project leaves with covers. Prefer JSR when you want versioned updates without re-extracting archives.
