✅ CLEAN MARKDOWN - NO MORE HTML POLLUTION! 🎉

Problem Identified & Fixed!

---

🔴 The Problem You Reported

What You Saw:

1. Click "Markdown" button
2. See HTML code with <p> and <br> tags ❌
3. Mixed HTML + markdown syntax (messy!)
4. Switch back to visual → More <p> and <br> added
5. Endless pollution! ❌

Root Cause:

// OLD (BROKEN) FLOW:
Visual Builder (blocks)
    ↓
blocksToHTML() → Adds <p> and <br>
    ↓
htmlToMarkdown() → Tries to clean, but messy
    ↓
"Markdown mode" shows: <p>, <br>, mixed syntax ❌

---

✅ The Solution

New Clean Flow:

// NEW (FIXED) FLOW:
Visual Builder (blocks)
    ↓
blocksToMarkdown() → Direct conversion!
    ↓
Markdown mode shows: Clean markdown ✅

Key Insight:

Skip HTML entirely when converting blocks ↔ markdown!

---

🛠️ What Was Built

1. New Function: blocksToMarkdown()

// Direct conversion: Blocks → Markdown (no HTML!)
export function blocksToMarkdown(blocks: EmailBlock[]): string {
  return blocks.map(block => {
    switch (block.type) {
      case 'card':
        return `[card type="${block.cardType}"]\n\n${block.content}\n\n[/card]`;
      case 'button':
        return `[button url="${block.link}"]${block.text}[/button]`;
      case 'divider':
        return '---';
      // ... etc
    }
  }).join('\n\n');
}

Result: Clean markdown, no <p>, no <br>! ✅

---

2. New Function: markdownToBlocks()

// Direct conversion: Markdown → Blocks (no HTML!)
export function markdownToBlocks(markdown: string): EmailBlock[] {
  const blocks: EmailBlock[] = [];
  
  // Parse [card] blocks
  const cardMatch = markdown.match(/\[card([^\]]*)\]([\s\S]*)\[\/card\]/);
  if (cardMatch) {
    blocks.push({
      type: 'card',
      cardType: extractType(cardMatch[1]),
      content: cardMatch[2].trim(), // Clean content!
    });
  }
  
  // ... parse other blocks
  
  return blocks;
}

Result: Direct parsing, no HTML intermediary! ✅

---

3. Updated EditTemplate.tsx

Before (BROKEN):

// Switching to markdown mode
const html = blocksToHTML(blocks);  // Adds <p>, <br>
const markdown = htmlToMarkdown(html); // Messy conversion
setMarkdownContent(markdown); // Shows HTML pollution ❌

After (FIXED):

// Switching to markdown mode
const markdown = blocksToMarkdown(blocks); // Direct, clean!
setMarkdownContent(markdown); // Shows clean markdown ✅

---

📊 Comparison

Old Flow (HTML Pollution):

Visual Builder
    ↓
Blocks: { content: "Hello world" }
    ↓
blocksToHTML()
    ↓
HTML: "<p>Hello world</p>"
    ↓
htmlToMarkdown()
    ↓
Markdown: "<p>Hello world</p>" ❌ Still has HTML!

New Flow (Clean Markdown):

Visual Builder
    ↓
Blocks: { content: "Hello world" }
    ↓
blocksToMarkdown()
    ↓
Markdown: "Hello world" ✅ Clean!
