**Error** from the compiler, while it builds your `.tsrx` files.

## What happened

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_SHARED_CALL_UNRESOLVED: `<callSource>` reaches no shared() definition. <resolves>
A call the compiler cannot resolve to a shared() definition creates no graph instance, so every read of it would render a dead value and every write would go nowhere — silently, at runtime.
Export the definition from the module this call names, and compile that module in this build. Before: `export const famState = shared(() => ..., { scope: 'widget' })` in `fam.tsrx` with nothing re-exporting it; after: `export { famState as state } from './fam.tsrx';` in the family index, so `fam.state()` names it.

Words in angle brackets change from case to case.

## How to fix it
