Issues fixed:
1. buildNPCs (and 23 other functions) were missing — lost when the ACT_DATA
block replacement accidentally deleted the switchAct→renderRefContent section
2. Duplicate const REF_DATA declaration (old literal + new JSON.parse version)
3. Stray </body></html> embedded inside the script content from prior botched edit
4. Final unescaped apostrophe: 'don\'t' in renderActContent
All 40 functions confirmed present. Node --check: ZERO SYNTAX ERRORS.
Root cause: ACT_DATA and REF_DATA objects were built using Python
string escaping that left unescaped apostrophes in single-quoted JS
strings (Reth's, entity's, don't, it's, Jed's, Sable's etc.) and
at least one unclosed template literal causing downstream parse failures.
Fix: ACT_DATA and REF_DATA are now stored as proper JSON in
<script type='application/json'> tags and loaded via JSON.parse().
All text content uses HTML entities for apostrophes and special chars.
Zero escaping ambiguity possible.
Node.js --check confirms: NO SYNTAX ERRORS.
Backtick count now 28 (even = all template literals properly closed).
