+// issue-0014: Feature request — {{{ CONTENT_HASH }}} template variable for wasm shell
+//
+// When targeting wasm, the compiler processes shell.html and substitutes
+// {{{ SCRIPT }}} with the <script> tag. Add a {{{ CONTENT_HASH }}} variable
+// that is a short hash (e.g. 8-char hex) of the final build outputs
+// (.js + .wasm + .data), so the shell can use it for cache busting:
+//
+//   <script>
+//   Module.locateFile=function(path){return path+'?v={{{ CONTENT_HASH }}}'};
+//   </script>
+//   <script async src="index.js?v={{{ CONTENT_HASH }}}"></script>
+//
+// This lets browsers cache until the next build, then bust automatically.
+// No changes needed to build.sx or modules/compiler.sx — just the compiler
+// recognizing the new placeholder during shell template substitution.
