Subject: [PATCH] fix(ci): regenerate gitignored CSS before unit-test Hugo
 build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

test/unit/hugo-homepage-partials.test.ts spawns a real Hugo build.
head.html:27 does `resources.Get "css/fundamental-styles-icon.css" |
minify | fingerprint`. Since ac6b7e39f stopped committing the generated
CSS (sap-fundamental.css, fundamental-styles-icon.css are now gitignored
build outputs), these assets are absent on a fresh checkout. unit-tests.yml
never regenerated them, so resources.Get missed the asset, minify got a
non-transformable resource.Resource, and the Hugo build exited 1 — failing
7 test files.

rebuild-content.yml already regenerates these before its Hugo build; this
mirrors that step (build:icon-subset + build:css) before npm test.

Verified: without the assets Hugo exits 1 (4 minify errors); after the two
gen steps Hugo exits 0 and hugo-homepage-partials.test.ts passes 4/4.
