Root cause: inline onclick with JSON.stringify(title) broke when title
contained quotes, special chars, or was empty. The HTML attribute parser
got confused by mismatched quotes, so click handler never fired.
Fix:
- Replaced inline onclick handlers with data-action attributes
- Added single delegated click listener at document level
- Title stored in element dataset (no HTML quoting issues)
- Added escapeHtml() helper for safe rendering of titles/errors
Now clicking Preview in the right sidebar opens the fullscreen modal
correctly, regardless of filename characters.
