🐛 Email Rendering Issues Fixed:
1. Markdown Not Parsed
❌ Raw markdown showing: ## Great news...
✅ Created MarkdownParser.php (PHP port from TypeScript)
✅ Parses headings, bold, italic, lists, links
✅ Supports card blocks and button syntax
✅ Proper newline handling
2. Variables Not Replaced
❌ {support_email} showing literally
✅ Added support_email variable
✅ Added current_year variable
✅ Added estimated_delivery variable (3-5 business days)
3. Broken Logo Image
❌ Broken image placeholder
✅ Fallback to site icon if no logo set
✅ Fallback to text header if no icon
✅ Proper URL handling
4. Newline Issues
❌ Variables on same line
✅ Markdown parser handles newlines correctly
✅ Proper paragraph wrapping
📦 New File:
- includes/Core/Notifications/MarkdownParser.php
- parse() - Convert markdown to HTML
- parse_basics() - Parse standard markdown
- nl2br_email() - Convert newlines for email
🔧 Updated Files:
- EmailRenderer.php
- Use MarkdownParser in render_card()
- Add support_email, current_year variables
- Add estimated_delivery calculation
- Logo fallback to site icon
- Text header fallback if no logo
🎯 Result:
- ✅ Markdown properly rendered
- ✅ All variables replaced
- ✅ Logo displays (or text fallback)
- ✅ Proper line breaks
- ✅ Professional email appearance
