Sveltekit Remote Functions

This covers SvelteKit's experimental remote functions feature, which lets you write server-only functions in .remote.ts files and call them directly from components as if they were local. You get four primitives: query() for reads, command() for mutations, form() for progressive enhancement, and prerender() for build-time data. The skill includes validation patterns with valibot or zod, batching to avoid n+1 queries, and a requested() mechanism for opt-in cache invalidation. It's current as of SvelteKit 2.58 and handles the quirks around serialization limits and refresh semantics. Useful if you're tired of writing both API routes and fetch calls for simple server interactions.
