- Switched template CSS/JS inlining replacements to callback form in generation scripts to avoid `$` replacement expansion semantics. - Updated HTML export generation to use callback-based replacements for theme variables and session data injection to prevent accidental `$` substitution parsing. - Added regression tests for the inlined script ensuring literal `$'` regex tokens remain intact, no closing HTML tags are injected, and the script parses via `new Function`.
