docs: fix typos and correctness issues in App Router docs (#97823) ## Summary A systematic review pass over the App Router documentation (`docs/01-app`, 281 MDX files) fixing clear-cut typos, grammar issues, and technical inaccuracies — code samples, file names, and API signatures that had drifted from the implementation in `packages/next/src`. The review ran four passes: an automated spell check with a triaged allowlist, targeted grammar-pattern searches, structural checks (frontmatter, code fences, link targets), and a technical-accuracy pass over all getting-started pages plus high-traffic API reference pages, with every suspected inaccuracy verified against the source before editing. Only unambiguous issues were fixed; anything debatable was deliberately left alone (e.g. the `/aboot` route in the typedRoutes docs is an *intentional* invalid-route example, and the CLI docs table intentionally mirrors the actual `--help` output). Notable fixes: - JSX examples now `await params`, matching the Promise-based API and their TypeScript counterparts - `generateStaticParams()` is now exported in samples so the convention actually takes effect - `<Link prefetch>` props table includes `"auto"`, matching the `boolean | "auto" | null` type in `link.tsx` - `Navigator.geolocation` casing, the canonical react.dev `"use client"` link, and a missing `Link` import in the typedRoutes docs - Mismatched or wrong `filename=` labels in TS/JS switcher pairs (`form.mdx`, `mutating-data.mdx`, `css.mdx`) and a wrong `generateStaticParams` anchor target - ESLint monorepo example registers the plugin as `@next/next` so the documented rule prefixes resolve - Spelling/grammar: `emphaize`, `invokations`, `behaviour` → American spelling, "setup" → "set up" as a verb (5×), "a RSC" → "an RSC", `NextJS` → `Next.js`, a stray comma, and "a `opengraph-image.tsx`" article plus its folder path ## Verification - `cspell` over all 281 files in `docs/01-app`: 0 issues outside a reviewed allowlist of product names, API identifiers, and intentional example strings - `prettier --check` (3.6.2, repo config): passes on all 19 changed files - Grammar-pattern and structure greps: clean - Technical claims cross-checked against `packages/next/src` and `packages/eslint-plugin-next` - Docs-only change; no runtime code touched <!-- NEXT_JS_LLM --> <!-- fleet eeae4385-18f5-406d-915e-986961503ed2 --> Co-authored-by: vercel-fleet-prod[bot] <318278635+vercel-fleet-prod[bot]@users.noreply.github.com> Co-authored-by: Tobias Koppers <1365881+sokra@users.noreply.github.com>
