 * CRITICAL: The :ssr suffix is required to avoid cache collisions with browser-mode transforms
 * that use relative paths (../lib/utils.js) instead of absolute paths (/_vf_modules/lib/utils.js).
 * CRITICAL: `dev` must stay part of this key. It feeds the distributed transform
 * cache, so a shared entry that dropped the compile mode would serve
 * development-compiled modules to hosted production renders across instances.
