/* ============================================================================
   MyNextOpp — frontend entry (Vite)
   ----------------------------------------------------------------------------
   This is the module Vite bundles. It:
     1. Imports the Career Intelligence enhancement layer (ESM) so it is
        included in the production build and tree-shaken.
     2. Boots the layer (UI panel + local-first notice) and attaches the public
        window.MNO_* globals for host/console compatibility.
     3. Logs the resolved API configuration so operators can confirm at a glance
        whether the build is wired to a backend or running standalone.

   The host React SPA is a separate, pre-built bundle loaded from /assets; this
   entry never imports it (it is not source). The two coexist: the host renders
   the app, the enhancement layer overlays Career Intelligence on top.
