Danny White 7d6995bbfe refactor(studio): clean up ProjectLayout title API (#43742)
## What kind of change does this PR introduce?

Refactor, cleanup, and docs update.

## What is the current behavior?

After the page-title rollout, `ProjectLayout` is still in a transitional
state:

- it accepts a deprecated `title` prop
- it still supports a separate `browserTitle.surface`
- wrapper layouts are split between passing `title` directly and passing
`browserTitle.section`

That makes the API harder to reason about than it needs to be, even
though the rendered titles are already correct.

## What is the new behavior?

This cleanup finishes the API simplification that came out of the
stacked PR review:

- wrapper layouts stay `title`-first for DX
- `ProjectLayout` no longer accepts `title`
- `product` is now the single source of truth for the project-surface
title segment
- `browserTitle` is now only used for extra browser-title metadata
(`entity`, `section`, `override`)
- the remaining project-scoped callers now pass `browserTitle.section`
when they need a section label
- docs now reflect the final pattern instead of the transitional one

Rendered page titles stay the same.

## Additional context

Checks run:

- `pnpm --filter studio exec vitest --run lib/page-title.test.ts
components/layouts/ProjectLayout/index.test.tsx`
- `pnpm --filter studio typecheck`
- `pnpm exec prettier --check ...` on touched files

This is intended as the post-rollout cleanup PR based on Joshen's review
feedback across the stacked title changes.

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly
const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}

export default ComponentA
