What is Fruitalytics Verify?
Batch analytics assertions: click a selector, require the events. Verification turns “we shipped tracking” into “tracking fires” — per release, automatically.

Visual Testing Agent
A preview-URL auditor that checks rendered pages like a visitor would. Read-only by default; writes structured findings the builder can act on.
Smoke Check (npm run check / build)
The cheapest reliable gate: typecheck plus production build. Run it after every structural change — it catches breakage code review would take ten times longer to find.
Engagement Rate
The share of sessions with meaningful interaction (time, scroll, events, conversions). GA4’s headline quality metric replacing bounce rate for most analysis.
Svelte Runes
The `$state`, `$derived`, `$effect`, and `$props` primitives powering Svelte 5 reactivity. Runes are mandatory in generated code: explicit, compilable, and consistent across every component.
File-Based Routing
Pages defined by file location: `+page.svelte` renders, `+layout.svelte` wraps, `+server.js` serves data. The route tree is the app map — no separate router config to drift.
Load Function
Server-side data loading for a route before it renders. Load on the server for content crawlers and users need immediately; reach for client fetching only for interactive extras.
