Build is failing, so this can't be merged as-is.

Failure (run #29170843790, bun run ci → astro check):

Cannot read properties of undefined (reading 'fileExists')
  at AstroCheck.getTsconfig (@astrojs/language-server/dist/check.js:162:73)

Root cause: TypeScript 7 changed its compiler/language-service architecture, and @astrojs/check (0.9.9) / @astrojs/language-server still depends on the legacy typescript API that TS 7 removed. astro check crashes before type-checking even runs — so this is not a code error in the site, it's a tooling incompatibility.

Options:

1. Wait for an @astrojs/check / @astrojs/language-server release that supports TypeScript 7, then re-run.
2. If TS 7 is needed now, temporarily pin typescript to ^6 (keep this update closed) until the language server is compatible.

Leaving as requesting changes until the build is green.

Closing: TypeScript 7 is not buildable with the current toolchain. astro check crashes on TS 7 (Cannot read properties of undefined 'fileExists' in @astrojs/language-server); @astrojs/check is already at latest (0.9.9) with no TS7-compatible release. Added a Renovate packageRule to block the typescript major bump until @astrojs/check supports v7 — remove the rule to re-enable.
