Svelte conventions

• .svelte files must be logic-less or logic-minimal. They should only render UI and wire props/stores together. Small presentational conveniences are fine (a display formatter, a class toggle, a UI-only animation, local open/closed modal state). Anything else, business/domain logic, async blockchain calls, transaction building, balance checks, data fetching/derivation, non-trivial computation, filtering/sorting/aggregating domain data, network error handling, belongs in a plain .ts module (a helper, a store, or a service) that the component imports.

• Never create .svelte.ts files. Do not use Svelte runes ($state, $derived, $effect, ...) outside of .svelte components. Put reusable logic in plain .ts files and expose reactivity with Svelte stores (writable/readable/derived from svelte/store). Components consume those stores with the $store syntax and own any $effect/lifecycle wiring themselves.

• Logic lives in .ts, reactivity crosses the boundary as stores. Prefer factory functions that return {subscribe, ...actions} (see the existing stores under src/lib/** and src/routes/**/lib/stores/).

The framework boundary

• Only web/src/lib/kit may import $app/*. Everything under web/src/lib/core takes what it needs from the framework as a parameter (PathResolver, ServiceWorkerEnvironment), and web/src/routes/** is exempt because routes are the framework's own surface. web/test/framework-boundary.test.ts enforces this and web/src/lib/kit/README.md states the scope, including what the rule deliberately does not cover.

• web/src/lib/index.ts is where the app is composed, which is why it may import both ./kit/* and the environment. Anything that composes THIS app belongs there rather than in core/.

• The two boundary tests and this section are INHERITED from template-svelte, the root of this template tree, where they are also enforced. A change to either that is meaningful for a sibling belongs there rather than here, or every sibling silently misses it.
