3f205627e0 feat(library): redesign the site around the block catalog (#50372)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Feature — the visual redesign itself.

Part 5 of 6 in a stack that splits the library redesign into reviewable
pieces. The four PRs beneath it carry the build, content and Markdown
work; what's left here is layout, navigation and styling.

## What is the current behavior?

The library is laid out like a documentation site: a sidebar tree of
framework folders, a homepage that lists links, and a guide page that
opens with prose. That shape suits reference material, but the library's
job is to help someone find a block and install it — and the sidebar is
the only way to discover one.

## What is the new behavior?

The homepage is the catalog itself — blocks grouped by what they do
(authentication, database, storage, realtime, messaging, AI,
foundations) rather than by framework, each with a preview of what it
renders, filterable by category.

Navigation moves into a site header whose Explore menu opens the same
categories, so the catalog is reachable from any page and the per-page
sidebar tree is gone.

A guide opens with what the reader came for: the block's name, the
install command, and a preview pane with tabs — the running component
and its files — before any prose. The file tree that used to sit
mid-page under "Folder structure" is one of those tabs. Every guide also
offers a copy of the agent prompt that points at its Markdown.

Getting-started pages get the same treatment: the quickstart is now a
framework-tabbed walkthrough rather than a wall of setup links.

## Additional context

`BlockOverviewTabs` renders Preview and Files here. #50369, stacked on
top of this one, adds the third "What's added" tab — it is the only part
of the redesign that depends on the new resource analyzer, which is why
it sits above this PR rather than below it.

Also removes what the redesign orphaned: the table-of-contents component
and its `remark` / `mdast-util-toc` dependencies, and the sidebar nav
and command-item configuration the new header replaced.

The block source changes are typography only — auth card titles move
from `text-2xl` to `font-medium text-lg tracking-normal` — which is what
regenerates the auth registry artifacts.

The [Supabase Community subscription template](https://github.com/supabase-community/nextjs-subscription-payments) includes authentication, subscription checkout, a customer portal, and database migrations. Its components and billing routes are installed together when you create the app.
## Installation
### Create the app
Scaffold the complete template with the [Next.js CLI](https://nextjs.org/docs/app/api-reference/cli/create-next-app):
```bash
npx create-next-app@latest my-saas --example https://github.com/supabase-community/nextjs-subscription-payments --use-pnpm
cd my-saas
```
The scaffold uses the template's dependency versions and includes its authentication implementation. Review dependency updates before deploying your app.
## Start Supabase
Install [Docker](https://docs.docker.com/get-started/get-docker/) and the [Supabase CLI](https://supabase.com/docs/guides/local-development/cli/getting-started). Copy the template's environment files, then start its local database and migrations:
```bash
cp .env.example .env
cp .env.local.example .env.local
pnpm supabase:start
```
Use the values printed by `pnpm supabase:status` to fill in `.env.local`:
```env
NEXT_PUBLIC_SUPABASE_URL=your-local-api-url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your-local-anon-key
SUPABASE_SERVICE_ROLE_KEY=your-local-service-role-key
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=your-stripe-test-publishable-key
STRIPE_SECRET_KEY=your-stripe-test-secret-key
STRIPE_WEBHOOK_SECRET=your-local-webhook-signing-secret
```
These names match the template. Keep `SUPABASE_SERVICE_ROLE_KEY`, `STRIPE_SECRET_KEY`, and `STRIPE_WEBHOOK_SECRET` in server environment variables.
## Connect Stripe
Install the [Stripe CLI](https://docs.stripe.com/stripe-cli), sign in, and keep webhook forwarding running in a separate terminal:
```bash
pnpm stripe:login
pnpm stripe:listen
```
Copy the listener's signing secret into `STRIPE_WEBHOOK_SECRET`. Start the app in another terminal:
```bash
pnpm dev
```
Load the template's sample test products after the app and webhook listener are running:
```bash
pnpm stripe:fixtures
```
Open [the app](http://localhost:3000), create an account, and test a subscription. Configure the [Stripe customer portal](https://dashboard.stripe.com/test/settings/billing/portal) to let customers change or cancel their plans.
## Deploy the app
Follow the template's [deployment setup](https://github.com/supabase-community/nextjs-subscription-payments#step-by-step-setup) for the hosted database, Auth URLs, production Stripe keys, and webhook endpoint. The template's [package scripts](https://github.com/supabase-community/nextjs-subscription-payments/blob/main/package.json) cover local migrations and billing fixtures.
