Winning projects

What strong projects actually look like — the question they asked, the design that survived review, and the one decision that made the difference.

Archive entries are summaries compiled for study. Read them for how a project was structured, argued, and defended — not as a template to reproduce. Copying someone else's project is the one thing that will end yours.
