Summary

For the code present, we get this error:

Cannot find namespace 'JSX'.

Fix it, verify, and then give a concise explanation. @components/landing.tsx:74-77

Readlanding.tsx317 lines

Checking how other components type React elements and how React 19 exposes JSX types:

GreppedJSX\.Element|React\.ReactElement|ReactElement

GreppedJSX

Checking React type exports:

Greppedexport.*ReactElement|export type.*Element

GreppedReactElement

Creating the plan:

Implement the plan as specified, it is attached for your reference. Do NOT edit the plan file itself.

To-do's from the plan have already been created. Do not create them again. Mark them as in_progress as you work, starting with the first one. Don't stop until you have completed all the to-dos.

Implementing the fix now: I’ll update the PricingFeature type to use ReactElement, then run a full typecheck to verify the error is resolved. I’ll also track progress in the existing to-dos as requested.

I found the exact JSX.Element usage and I’m applying the targeted type-only import plus prop type update now.

Edited

Fixed the JSX namespace error in components/landing.tsx by replacing the type usage that relied on global JSX:

Added import type { ReactElement } from "react";
Changed feature: { icon: JSX.Element; label: string } to feature: { icon: ReactElement; label: string }

Verification:

Ran bun run typecheck (tsc --noEmit) successfully with exit code 0
Checked lints for components/landing.tsx: no linter errors

Why this works:

With the automatic JSX runtime ("jsx": "react-jsx"), the global JSX namespace may not be available in all contexts. Using ReactElement from react is the correct explicit type and avoids that namespace resolution issue.
