hey! If you've worked on Tizen and Firefox previously then you're way ahead of me!

For Svelte 5 not having been trained into LLMs yet, I know what you mean. It's a frequently recurring thread on the Svelte Discord channels.

Two potential options for that:

1. LLM-friendly codified version of the Svelte docs: https://svelte.dev/docs/llms
2. ChatGPT specific Svelte docs to include in context: https://chatgpt.com/g/g-Knj6VxTpl-svelte-5-sveltekit-sage

I use Claude more than any other LLM so I can't say if either of the two options above are effective.

Sorry for the noob question, but that diagram - how do i zoom in on it?

No worries, I think I'm the one with a mermaid graph obsession.

It depends on the browser but usually on the Github website there should be controls in a bottom-right overlay on the diagram to move around and zoom in/out.

But honestly it's way more convenient to just copy the raw diagram code and paste it into a full-screen markdown editor (i mockup all my diagrams in Obsidian).

haha, no sorry haven't worked on neither of those places - just considering that they've might have concepts that one could jack in to. touch-interaction / display / events etc - Maybe back to Xerox PARC?! :) So finding the long-life concepts - and mapping those to Svelte bits. :)

Ok gotcha, understood 👍
