The prior dance (93bb94a12 drop .ts, bb278fb3c switch to .js) kept
breaking one consumer or the other:
- bare specifiers (no extension) satisfied svelte-check but broke the
Node ESM loader invoked via @tailwindcss/node during SSR — SSR of
every (app) route 500'd with ERR_MODULE_NOT_FOUND on 'theme'.
- .js extensions satisfied svelte-check and Vite but still broke the
Tailwind loader, because the files on disk are .ts — Node ESM walks
the actual filesystem and can't rewrite .js → .ts the way tsc does
at type-check time.
Flip the web app's tsconfig to "allowImportingTsExtensions": true and
put the .ts extensions back. tsc now accepts the imports, and Node's
loader finds the real file on disk. No build step, no emit, and the
shared-types package stays a pure source-only TS workspace.
