Ship a Multi-Page Site
By the end a three-page site for your tier-1 client is live at a public address on GitHub Pages: three pages, one nav copied exactly, one stylesheet, relative paths only, index.html at the root. The frame shipped first and the pages grew under direction with a receipt each; the deploy checklist ran with check-scs2.3 --url and one failure was read before anything was touched; the content is the owner's, confirmed and logged, or a marked placeholder in square brackets, never invented; the stranger test passed on a partner's phone; and a Definition of Done a stranger could check is signed by you and a partner.
