# 🔧 Fixes Applied - Product Tables & Responsive Fonts

## ✅ Issue 1: Product Tables Disappeared

### Problem
The product specification tables (extracted from images) were not showing on product pages in the Astro migration.

### Root Cause
- The Astro product detail page template (`[slug].astro`) was missing
- Product tables data exists in `src/data/site-config.ts` but wasn't being rendered
- Markdown files don't include table data (tables are in TypeScript file)

### Solution
Created `src/pages/products/[slug].astro` with:
1. **Table Rendering Section** - Displays all `productTables` from site-config
2. **Proper Styling** - Matches original Next.js design with:
   - Table name headers
   - Alternating row colors
   - Responsive table containers
   - Proper borders and shadows

### Code Added
```astro
{productTables.length > 0 && (
  <section class="mb-12">
    <h2>ตารางข้อมูลผลิตภัณฑ์</h2>
    {productTables.map((table) => (
      <div class="bg-white rounded-2xl...">
        <h3>{table.tableName}</h3>
        <table>
          <thead>{table.headers.map(...)} </thead>
          <tbody>{table.rows.map(...)} </tbody>
        </table>
      </div>
    ))}
  </section>
)}
```

### Data Source
Tables are loaded from `src/data/site-config.ts` via `productCategories.find(p => p.id === product.data.id).productTables`

Products with tables:
- ✅ ppr-welder (1 table)
- ✅ poloplast (4 tables)
- ✅ syler (2 tables)
- ✅ xylent (3 tables)
- ✅ pvc/upvc (6 tables)
- ✅ realflex (3 tables)

## ✅ Issue 2: Font Too Small on Large Screens

### Problem
Text was not scaling properly on larger screens (desktop, 4K monitors).

### Root Cause
- Base font size was fixed at browser default (16px)
- No responsive scaling for larger viewports
- Tailwind classes weren't enough for very large screens

### Solution
Added responsive font scaling in `src/styles/global.css`:

```css
/* Base font size */
html {
  font-size: 16px;
}

/* Scale up for larger screens */
@media (min-width: 1280px) {
  html { font-size: 18px; }
}

@media (min-width: 1536px) {
  html { font-size: 20px; }
}

@media (min-width: 1920px) {
  html { font-size: 22px; }
}

@media (min-width: 2560px) {
  html { font-size: 24px; }
}
```

### Additional Responsive Text Classes
```css
.text-responsive-sm   { text-sm md:text-base lg:text-lg xl:text-xl; }
.text-responsive-base { text-base md:text-lg lg:text-xl xl:text-2xl; }
.text-responsive-lg   { text-lg md:text-xl lg:text-2xl xl:text-3xl; }
.text-responsive-xl   { text-xl md:text-2xl lg:text-3xl xl:text-4xl; }
```

### Updated Components
All major text elements now use responsive sizing:
- **Buttons**: `text-base md:text-lg`
- **Section titles**: `text-3xl md:text-4xl lg:text-5xl xl:text-6xl`
- **Table headers**: `text-xl md:text-2xl lg:text-3xl`
- **Table cells**: `text-base md:text-lg lg:text-xl`
- **Features/FAQ**: `text-base md:text-lg lg:text-xl`
