Claude Code Landing Page Build with 3 Plugins

Build me a landing page for a developer tool called Flux. Before you touch any code, use frontend-design to pick a single real aesthetic and lock it in (brutalist, editorial, minimal or retro - commit to one). Then use superpowers to plan the full component tree, write component tests first, build each component to pass those tests, and run a code review pass before you finalize. For every library and API call, use context7 to confirm the current documentation and refuse to use any method that is not in the latest docs. Do not ship anything. Show me the plan first. When I approve, build. When the build passes tests, show me the final diff for one more approval before writing it to disk.
