- Fixed fragmented conditional blocks that were generating invalid JavaScript syntax
- Consolidated edit mode initialization logic into cohesive if/try/catch blocks
- Added proper class definition placement at script top level
- Implemented progressive enhancement with graceful degradation (content always displays)
- Added step-by-step status reporting and user-friendly error messaging
- Fixed timeout functionality for edit mode initialization tracking

The edit mode now properly initializes with transparent error reporting while maintaining
content visibility even when JavaScript fails, addressing user feedback for better
debugging and user experience.

a350b96dd2 feat: implement graceful degradation and error reporting for md-render --edit
Complete redesign of edit mode using progressive enhancement principles:

ALWAYS WORKS:
- Content is rendered server-side first (like regular mode)
- Visible even if JavaScript completely fails
- Fallback rendering if CDN is blocked

USER-FRIENDLY ERROR REPORTING:
- Visual status indicator shows edit mode state
- Clear error messages displayed on page (not just console)
- Browser info and GitHub issue link for bug reports
- Helps users understand what's happening and how to help

PROGRESSIVE ENHANCEMENT:
- Step 1: Render content (guaranteed to work)
- Step 2: Try to add edit capabilities (bonus feature)
- If Step 2 fails, users still get full content + clear explanation

This solves the core issue where users got blank pages when JavaScript
failed, and provides much better debugging information for future issues.

Addresses feedback on #154: Html generated by "md-render --edit" does not show in firefox

0d60dc73bd fix: resolve JavaScript syntax error in md-render --edit mode fallback
Fixed critical JavaScript syntax error in the markdown fallback parser where
literal newlines were being inserted into regex patterns, breaking JavaScript
execution entirely in edit mode.

Root cause: The f-string template was inserting actual newline characters
instead of escaped \n sequences in the regex .replace(/\n\n/g, ...) pattern,
causing invalid JavaScript that prevented any script execution.

Changes:
- Fixed regex patterns to use proper escape sequences (\n\n instead of literal newlines)
- Fixed asterisk escaping in bold/italic patterns (\*\* instead of **)
- Removed excessive debug logging for cleaner production code
- Maintained essential error handling for CDN loading failures

The --edit mode should now work correctly in Firefox and other browsers.

be8bbbb537 fix: resolve Firefox display issue in md-render --edit mode
Fixed JavaScript execution order problem where MarkitectEditor class
was being instantiated before it was defined, causing Firefox to fail
rendering the HTML page.

Changes:
- Moved editor script definitions before DOMContentLoaded event handler
- Ensured proper script execution sequence for cross-browser compatibility
- Maintained existing functionality for regular (non-edit) mode rendering
