/** Cross-framework externals for SERVER (Bun-target) page bundles.
 *
 *  `@absolutejs/absolute`'s internals reference every framework's runtime
 *  transitively (react-dom/server, svelte/server, @angular/core, …). A
 *  single-framework project only has its own framework installed, so these
 *  specifiers must stay bare — resolved (or harmlessly absent) at runtime —
 *  instead of failing the bundle at build time with "Could not resolve".
 *
 *  The initial build always used this list (core/build.ts); the dev bundle
 *  rebuilds only externalized their own framework's packages, which meant a
 *  vue-only project's SSR rebuild failed on react/svelte/angular imports on
 *  EVERY edit — silently, before soft-failure logging landed — and the dev
 *  server served boot-time SSR bundles until restart. */
