tsconfig.json only includes src, so vite.config.mts isn’t type-checked by npm run type-check. Since this PR renames build.rollupOptions to build.rolldownOptions, a typo or unsupported option here could silently disable external handling and change the library bundle output. Consider adding a dedicated type-check step for vite.config.mts (or including config files in a separate tsconfig) to catch invalid config keys during CI.

Bumping to vite@8.0.5 raises the required Node.js engine (^20.19.0 || >=22.12.0 per the installed package metadata). If your CI/dev environments rely on older Node versions, installs/builds will fail. Consider declaring an engines.node constraint in package.json (and/or updating CI tooling) so the requirement is explicit.
