// Build an opt-in production bundle WITHOUT changing runtime semantics.
|
|
//
|
|
// The feature modules share a single global scope and are executed in a fixed order
|
|
// (see loader.js). We therefore CONCATENATE them in that exact order into one file and
|
|
// minify whitespace/syntax only — identifiers are kept, because inline HTML handlers
|
|
// (onclick="navTo(...)") and cross-file references rely on global names.
|
|
//
|
|
// Run: npm run minify → static/dist/main.min.js
|
|
// Enable at runtime with window.APP_USE_BUNDLE=true (or ?bundle=1). Default stays
|
|
// per-file so editing static/js/* is live without a rebuild.
