Svelte compiles your components to vanilla JavaScript at build time. No virtual DOM, no runtime framework. The result is smaller bundles, faster performance, and simpler code. SvelteKit adds routing, SSR, and full-stack capabilities. This skill covers Svelte 5's runes (the new reactivity system), SvelteKit routing, form actions, load functions, and deployment.
