Type Alias Signal<T>

vapor-chamber — minimal signal abstraction.

Standalone module with NO module-load side effects. Imported by transports, plugins, form — modules that need a signal API but should not drag the full Vue feature-detection registry from chamber.ts into ESM consumer bundles.

Detection strategy:

1. Lazy sync probe of globalThis.__VUE__ on first signal() call — catches the MPA / server-rendered-page case where Vue is loaded as a global via <script> tag before vapor-chamber initializes.
2. Plain getter/setter fallback otherwise.
3. configureSignal(fn) lets chamber.ts push Vue's ref() here once its async dynamic import resolves, so SPA consumers eventually use the alien-signals-backed ref for real reactivity.

Consumers needing full Vue auto-detection (async probe, Vapor detection, lifecycle hooks) import from chamber.ts, which calls into this module.
