❌ Not mergeable — TypeScript 7 is the native compiler without the JS compiler API

typescript@7.0.2 is the Go-native compiler. It typechecks fine as a CLI, but its npm package no longer ships the JS compiler API this repo depends on. Three independent failures, all reproduced locally:

1. pnpm typecheck fails on this branch itself — tsc resolves the typescript import to a stub and reports e.g.
   Property 'forEachChild' does not exist on type 'typeof import(".../typescript@7.0.2/.../lib/version")'
2. tests/app/i18n-text-literals.test.ts crashes at runtime (the CI quality failure): the hardcoded-English guard walks the TS AST and dies at ts.SyntaxKind.AmpersandAmpersandToken (ts.SyntaxKind is undefined). Its sibling attr-literals scanner is regex-based, but this one is deliberately AST-based per its header comment — it can't run without the API.
3. preview-image fails: pnpm build (next build) exits 1 inside Docker — Next 16.2.x's TS integration expects the TS 5/6 API surface as well.

Suggested handling: close this PR and leave the major unapproved on the Dependency Dashboard (or add a packageRules entry disabling typescript majors) until (a) the native compiler ships its API-compatibility layer and (b) Next supports it. The i18n AST tests give this repo a harder-than-usual dependency on the old API, so this isn't a "fix one test" situation.

Diagnosis, since this one is failing for a different reason than the others right now:

• The quality failure is the repo-wide postcss advisory — fixed in fix(deps): raise the postcss floor to 8.5.18 (unblocks all CI) #141, unrelated to this upgrade.
• The preview-image failure is genuine to TypeScript v7 and won't clear by rebasing. The Docker build dies during pnpm build with:

The "id" argument must be of type string. Received undefined
Next.js build worker exited with code: 1 and signal: null

That's Next 16's build worker choking on the v7 compiler, not a code problem in this repo — note pnpm typecheck itself is fine, so it's the bundler integration rather than our types.

Suggest holding this one until Next ships explicit TypeScript 7 support, rather than trying to work around it. Worth re-testing after the next Next.js minor.
