hello.

One-time setup (3 mins) — do this once:
1. Supabase: supabase.com → New Project (free)
SQL Editor → Run:
create table listings (id uuid primary key default gen_random_uuid(), title text not null, price numeric not null, region text, category text, description text, image_url text, stripe_price_id text, created_at timestamp default now()); alter table listings enable row level security; create policy "public read" on listings for select using (true); create policy "public insert" on listings for insert with check (true); Storage → New Bucket: listing-images → Public ON
2. Stripe: dashboard.stripe.com → Developers → API keys → copy Secret key sk_live_...
Supabase → Edge Functions → New Function: create-checkout → Paste code from below file supabase/functions/create-checkout/index.ts (I give you file)
Supabase → Project Settings → Edge Functions → Secrets → Add: STRIPE_SECRET_KEY = your sk_live_... + SITE_URL = https://lucksureheis.github.io/Wave-hello/
3. Paste keys here:
Save & Connect

Edge Function code — 75c LIST + 75c SALE = $1.50 — supabase/functions/create-checkout/index.ts
