`npm run check` reported 15 errors and `npm run lint` 20, all pre-existing, so
neither gate could pass. Fixing them turned up three real bugs:
- SignOut destructured `{ error }` off `.then(() => {})`, which resolves to
undefined, so every sign-out threw a TypeError - after the signed-out event had
already been emitted. Sign-out also left the user on the protected page they
were on, still showing its content; it now returns them to the home page and
re-runs the server loads.
- SignUp passed `redirectTo`, which is not a signUp option and was silently
ignored, so the confirmation link has always used Supabase's configured site
URL. Documented rather than changed, since pointing it elsewhere needs an
absolute allow-listed URL.
- The Pokédex page tracked totalRecordsCreated but never passed it to the box
view, so the "Processed N entries so far" progress message never rendered.
The rest is typing and dead code: cookie callback parameters in hooks.server.ts
and +layout.ts, the untyped supabase props, a query-builder type that made
PostgREST rows untyped downstream, an unused session destructure, and
`while (true)` paging loops rewritten as `for (;;)`.
It turns out that tailwind excludes styles it hasn't found in use, so it needs to be explicitly told where to find the component files. This also therefore fixes the styles in the SignUp component.
