The Guestbook

⚙️ One-time setup to go live

Right now this book isn't connected to a database yet, so messages can't be shared. Do this once (all free):

1. Make a free account at supabase.com → New project.
2. Open SQL Editor, paste and run this:

   create table guestbook (
     id bigint generated always as identity primary key,
     name text not null,
     message text not null,
     created_at timestamptz default now()
   );
   alter table guestbook enable row level security;
   create policy "anyone can read"  on guestbook for select using (true);
   create policy "anyone can sign"  on guestbook for insert with check (
     char_length(name) between 1 and 40
     and char_length(message) between 1 and 500
   );

3. Go to Project Settings → API (or the Connect dialog). Copy your Project URL and your publishable / anon public key.
4. Open this HTML file and paste them into the CONFIG block near the bottom (SUPABASE_URL and SUPABASE_KEY). Save & re-upload.

That's it — after that, anyone who signs will show up for everyone. (The publishable key is safe to put in the page; your data stays protected by the policies above.)
