Option 2: "What we fixed"

v1.9 is live.

We had "no signup required" on the site but required sign-in to run. That's fixed: one message everywhere. Sign in to run your first analysis. 5 free per month.

We also made the result one report first — Summary through Evidence — with deeper insights (benchmarks, plan) in one section. Same pipeline, clearer read.
