/**
* Canonical CORS configuration for Supabase Edge Functions
*
* This module exports CORS headers that stay synchronized with the Supabase SDK.
* When new headers are added to the SDK, they are automatically included here,
* preventing CORS errors in Edge Functions.
*
* @example Basic usage
* ```typescript
* import { corsHeaders } from '@supabase/supabase-js/cors'
*
* Deno.serve(async (req) => {
*   if (req.method === 'OPTIONS') {
*     return new Response('ok', { headers: corsHeaders })
*   }
*
*   return new Response(
*     JSON.stringify({ data: 'Hello' }),
*     { headers: { ...corsHeaders, 'Content-Type': 'application/json' } }
*   )
* })
* ```
*
* @module cors
