Add shadcn/ui plumbing:
- components.json (style: new-york, baseColor: slate, primary: green ~142 71%)
- src/lib/utils.ts with cn() helper (clsx + tailwind-merge)
- Tailwind config switched to CSS variables theming with primary/destructive/
muted/card etc. tokens, dark-mode class, tailwindcss-animate plugin
- src/styles/globals.css declares :root and .dark variable palettes
Initial component set under src/components/ui:
- Button (cva variants: default/destructive/outline/secondary/ghost/link, asChild)
- Input
- Label (Radix Label)
- Card + CardHeader/Title/Description/Content/Footer
Refactor existing auth surface to the new primitives:
- sign-in / sign-up pages wrap form in a Card with Title/Description (+ footer
for sign-up disclaimer)
- sign-in-form / sign-up-form use Input, Label, Button; tokens replace bespoke
emerald/slate classes; divider and "Continua con Google" use the same Button
- Home page CTAs become Button asChild around Link; SignOutButton uses Button
- Hide-Google logic still works: enabledSocialProviders is now
ReadonlyArray<SocialProvider> for ergonomic .includes() checks
