 - Never use supabse-js. I am using supabse-ssr and supabase client is located in:
   - client: $props.data.supabse
   - server: $locals.supabase
+- Avoid unnceessary iterations. Once the problem is solved, ask me if i want to to continue and only then continue iterating.
+- Avoid sweeping changes throught the project. If you want to change something globally, ask me first.
 
 Do not fall back to the legacy $: label syntax or Svelte 3/4 stores! This is important!
