Dogfood content for every template family

The site now ships real blog, tutorial, resume, author, and changelog pages.

Added

Every shipped template family now has live content, so each family renders on the public site instead of returning a 404:

  • A blog with three posts and a team author.
  • A two-step tutorial with a progress stepper.
  • A one-page resume profile.
  • An authors index and profile page.
  • This changelog.

Why

The templates existed but had nothing to render. Standing up minimal, real content makes the capabilities discoverable from navigation and guards them with a build test, so a future change that breaks a family fails CI instead of shipping quietly.
