Driver

In the quickstart on site/index.html, step 02 ("claude, /setup") is a code block that starts with claude. But the reader is only implicitly in the apexyard directory from step 01. Making the step self-contained is clearer pedagogy.

Scope

Change step 02 code block from:

claude
/setup
# three questions → onboarding.yaml is configured

to:

cd apexyard
claude
/setup
# three questions → onboarding.yaml is configured

One-line edit in site/index.html.

AC

• Step 02 code block starts with cd apexyard
