// Target: http://localhost:3000

1. Replace generic headline "Empower your workflow with seamless AI" with concrete friction:
   "Stop reconciling CSVs across four tools. Automated webhooks alert engineers in Slack before errors hit production."
2. Delete radial purple gradient halo backdrop (.bg-gradient-to-r from-purple-600 to-indigo-600). Anchor layout on solid paper (#FAF8F5) with 1px structural ink borders.
3. Replace centered vacuum layout with an asymmetric 7/5 column grid. Place verifiable latency benchmarks in the right column.
Automated Session Sync
