host: blog home page GET / -> HTML post index, 179/179
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 41s
Details

Browse Source 
GET / renders an HTML index listing every post (title linking to /<slug>/),
built from host/blog-list; empty -> 'No posts yet'. GET /posts stays the JSON
API. Live: blog.rose-ash.com/ lists the welcome post linking to /welcome/.
