/**
 * context(justinvdm, 2025-05-14):
 *
 * ## Problem
 * React Server Components (RSC) and traditional SSR require different module
 * resolution:
 * - RSC modules must resolve with the "react-server" export condition
 * - SSR modules must resolve without it
 *
 * This presents a challenge for our framework, where the same modules often
 * need to run in both modes — within a single Cloudflare Worker runtime. We
 * can't split execution contexts or afford duplicated builds.
 *
 * Vite provides an elegant way to manage distinct resolution graphs via its
 * `environments` feature (`client`, `ssr`, `worker`, etc.). Each environment
 * can use different export conditions, plugins, and optimizeDeps configs.
 *
 * However, using separate environments implies separate output bundles. In our
 * case, that would nearly double the final bundle size — which is not viable
 * given Cloudflare Workers' strict 3MB limit.
 *
 * ## Solution
 * We run both RSC and SSR from a single Vite `worker` environment. To simulate
 * distinct resolution graphs, we virtualize SSR imports using a prefix.
 *
 * How it works:
 * - Maintain an SSR subgraph as part of the worker environment's module graph.
 *   Any time we see "use client", we enter the subgraph.
 * - We keep the graphs separate by rewriting imports in SSR graph to map to virtual files.
 * - Bare imports to deps get resolved using a custom resolver so that we use
 *   import conditions relevant to SSR - note the lack of "react-server"
 *   condition: ["workerd", "edge", "import", "default"]
 * - All imports within the subgraph get their path rewritten with the SSR
 *   module namespace prefix so that we stay within the subgraph.
