This is a focused reference for Svelte 5 runes mode in Epicenter apps. It pushes you toward $state, $derived, and snippets while steering you away from legacy $: and slots. The real value is in the specific guidance: when to use keyed blocks for resource lifecycles, how to wire TanStack Query mutations directly in templates, when SvelteMap beats a plain array, and why commit-on-blur is better than firing workspace writes on every keystroke. It also covers shadcn-svelte integration and includes upstream grounding through DeepWiki when compiler behavior matters. Written for teams that already know Svelte but need consistent patterns across a shared codebase.
