Clarify interactive script workflow - students open HTML files

Made it explicit that:
1. Script tells them which HTML file to open
2. Students open and look at the file
3. Script asks questions about what they see
4. Much clearer than 'guide you through results'

Now students know they'll be actively looking at HTML reports!
