Build a complete, modern, premium and production-ready web application called:

“Vintage Postcard”

Tagline:
“পুরনো দিনের অনুভূতি, আজকের ভালোবাসার জন্য।”

The website should be a beautiful Vintage Love Postcard Generator where users can select from many pre-designed vintage postcards, choose romantic quotes, write their own text, customize the text, preview the postcard and download it in HD.

IMPORTANT:
- Do NOT include any user photo upload feature.
- Do NOT include photo editing.
- Do NOT require users to upload their own images.
- All postcard artwork/images should be pre-designed and included in the website.
- The core experience must be extremely simple:
  Select Postcard → Select Quote OR Write Your Own → Customize → Preview → Download.
- The website must work beautifully on desktop, tablet and mobile.
- UI language should primarily be Bengali, with some English labels where appropriate.
- The visual style should be premium, elegant, dark vintage and romantic.

==================================================
1. BRAND / VISUAL IDENTITY

==================================================
2. HOMEPAGE
==================================================

Create a visually impressive homepage.

Hero section:

Logo:
💌 Vintage Postcard

Headline:
“পুরনো দিনের অনুভূতি,
আজকের ভালোবাসার জন্য।”

Subheadline:
“আপনার প্রিয় মানুষটির জন্য তৈরি করুন একটি সুন্দর Vintage Postcard।”

Primary CTA:
“✨ পোস্টকার্ড তৈরি করুন”

Secondary CTA:
“🖼️ Vintage Gallery দেখুন”

Add a beautiful vintage postcard preview beside the hero text.

Below hero:

Category section:

“ক্যাটাগরি বেছে নিন”

Categories:

❤️ প্রেম
🌹 রোমান্টিক
💔 বিরহ
🥺 মিস করা
🌧️ বৃষ্টি
🌙 রাতের অনুভূতি
💌 প্রেমপত্র
💍 প্রপোজ
🎂 জন্মদিন
💑 Anniversary
🖤 একতরফা প্রেম
🌸 স্মৃতি
🎞️ Classic Vintage
🇧🇩 Bengali Vintage

Each category should be clickable and filter postcard templates.

==================================================
3. FEATURED POSTCARDS
==================================================

Create sections:

“🔥 জনপ্রিয় পোস্টকার্ড”

“✨ নতুন পোস্টকার্ড”

“❤️ Romantic Collection”

“🌧️ Rainy Love Collection”

“💌 Vintage Letter Collection”

Display beautiful postcard cards.

Each card should show:
- Vintage artwork
- Short quote preview
- Category
- Favorite icon
- “ব্যবহার করুন” button

When clicking “ব্যবহার করুন”, open the Postcard Generator with that template selected.

==================================================
4. POSTCARD TEMPLATE LIBRARY
==================================================

Create a large searchable template library.

Include many placeholder/demo postcard designs.

Categories:

Romantic Couple
Old Love Letter
Rose
Rain
Umbrella
Moonlight
Railway Station
Old Café
Vintage House
Cinema
Nature
Lake
River
Sunset
Coffee
Flowers

Each template should have:
- Unique ID
- Category
- Background image/artwork
- Default quote
- Text position
- Default typography
- Border style

IMPORTANT:
Use local assets/placeholders in the project architecture so that I can later replace them with my own generated vintage artwork.

Create the data structure cleanly so adding 100+ templates later is easy.

==================================================
5. POSTCARD GENERATOR
==================================================

Create a dedicated page:

“💌 Vintage Postcard Generator”

Step 1:
“১. পোস্টকার্ড নির্বাচন করুন”

Show template thumbnails.

Step 2:
“২. উক্তি নির্বাচন করুন”

Show ready-made quotes.

Example quotes:

“তোমাকে পাওয়ার জন্য নয়, তোমাকে একদিন ভালোবেসেছিলাম—শুধু ভালোবাসার প্রয়োজনে।”

“কিছু মানুষ জীবনে আসে, থেকে যাওয়ার জন্য নয়—মনে থেকে যাওয়ার জন্য।”

“তুমি কাছে না থেকেও আমার প্রতিটি গল্পের সবচেয়ে সুন্দর অংশ।”

“ভালোবাসা কখনো পুরনো হয় না, শুধু স্মৃতিগুলো আরও গভীর হয়।”

“তোমার কথা মনে পড়লে পুরনো দিনের চিঠিগুলোও যেন কথা বলে।”

Add many demo Bengali romantic quotes.

Each quote should have:
[ ব্যবহার করুন ]

Also add:
“🎲 Surprise Me”

This should randomly select:
- postcard
- quote
- suitable typography

==================================================
6. CUSTOM TEXT
==================================================

Add:

“✍️ অথবা নিজের লেখা লিখুন”

Large textarea:

“এখানে আপনার নিজের লেখা লিখুন...”

Buttons:
“লেখাটি ব্যবহার করুন”

The user should be able to:
- Use a ready-made quote
- Edit a ready-made quote
- Completely replace it with their own text

Text fields:

প্রাপক:
[ প্রিয়তমা ]

মূল লেখা:
[ textarea ]

প্রেরক:
[ ইতি, তোমার... ]

তারিখ:
[ optional ]

==================================================
7. TEXT CUSTOMIZATION
==================================================

Keep the editor simple, not like Canva.

Controls:

Font Family
Font Size
Bold
Italic
Text Alignment
Letter Spacing
Line Height
Text Color
Text Position

Available font styles:
- Elegant Bengali
- Handwritten
- Vintage Serif
- Typewriter
- Classic
- Calligraphy
- Old Newspaper

Add:
Reset Text Style

The preview should update instantly.

==================================================
8. POSTCARD PREVIEW
==================================================

Create a large live preview.

The selected postcard should appear realistic.

Include:
- Vintage artwork
- Decorative border
- Quote
- Recipient
- Sender
- Optional date
- Small decorative stamp/seal

The user should see exactly what will be downloaded.

Do not make the editor unnecessarily complicated.

==================================================
9. VINTAGE EFFECTS
==================================================

Add simple visual options:

Original
Sepia
Old Paper
Faded
Black & White
Film Grain
Dust
Scratch
Coffee Stain
Warm Vintage

These effects should apply to the postcard preview.

Keep effects subtle and premium.

==================================================
10. VINTAGE QUOTE GALLERY
==================================================

Create a separate section:

“🖼️ Vintage Quote Gallery”

These are PRE-MADE artwork images that already contain beautiful small text.

Examples:

“Some stories never end.”

“Forever begins with a memory.”

“তুমি ছিলে, তাই গল্পটা সুন্দর ছিল।”

“কিছু স্মৃতি কখনো পুরনো হয় না।”

These gallery items are NOT editable.

They are simply:
View → Download

Create many categories and placeholder artwork entries so I can later add my own generated images.

==================================================
11. SEARCH
==================================================

Add a global search box:

“উক্তি বা পোস্টকার্ড খুঁজুন...”

Search should work across:
- postcard templates
- quotes
- categories
- vintage gallery

Example:
Search “বৃষ্টি”
→ show rainy postcards and rainy quotes.

==================================================
12. FAVORITES
==================================================

Allow users to favorite:
- postcards
- quotes
- gallery images

Use localStorage for the initial version.

Create:
“♡ আমার পছন্দ”

No mandatory login should be required.

==================================================
13. DOWNLOAD SYSTEM
==================================================

Main button:

“⬇️ HD পোস্টকার্ড ডাউনলোড করুন”

The generated postcard must be downloadable as:
- PNG
- JPG

Default download quality:
High resolution / HD.

Use a reliable client-side rendering/export method such as:
html2canvas or an equivalent suitable browser-side solution.

The downloaded image should NOT contain:
- website UI
- editor controls
- buttons
- watermark

Only the postcard itself should be exported.

==================================================
14. DOWNLOAD AD GATE
==================================================

IMPORTANT.

Before EVERY postcard download, show a download gate modal.

When user clicks:
“⬇️ HD পোস্টকার্ড ডাউনলোড করুন”

DO NOT download immediately.

Open a premium-looking modal.

Title:
“💌 আপনার পোস্টকার্ড প্রস্তুত”

Text:
“ডাউনলোড চালু করার আগে Sponsor Page দেখুন।”

Button:
“👁️ Sponsor দেখুন”

Sponsor URL:

https://femalesfellowship.com/a0fkrfvyar?key=2e964f9cdd62c95c757c3b899a253e58

When the user clicks the Sponsor button:
- Open the URL in a new browser tab/window where browser policies permit.
- Keep the postcard generator page open.
- Start an 8-second countdown.

Countdown:

8
7
6
5
4
3
2
1

During countdown:

“Download প্রস্তুত হচ্ছে...”

The download button must remain disabled during countdown.

After countdown:

Show:

“✅ Download Ready”

Button:
“⬇️ DOWNLOAD NOW”

Only after the countdown finishes should the download button become active.

IMPORTANT TECHNICAL NOTE:
Do NOT claim that the website can verify whether the user actually watched the external advertisement for 8 seconds. The website should simply implement the 8-second download gate and open the sponsor URL.

The sponsor URL must be configurable from one central configuration variable so it can easily be changed later.

Example architecture:

const SPONSOR_URL = "YOUR_URL_HERE";

Do NOT hardcode the URL in multiple places.

Every new download attempt should trigger the download gate again.

==================================================
15. DOWNLOAD MODAL DESIGN
==================================================

Make the modal match the website.

Dark vintage background.

Gold thin border.

Small vintage decorative elements.

Countdown should be visually prominent.

Example:

💌 POSTCARD READY

আপনার Vintage Postcard প্রস্তুত।

Sponsor Page খুলুন এবং কয়েক সেকেন্ড অপেক্ষা করুন।

[ 👁️ Sponsor দেখুন ]

       08

Download প্রস্তুত হচ্ছে...

[ 🔒 Download Locked ]

After countdown:

       ✓ READY

[ ⬇️ DOWNLOAD NOW ]

==================================================
16. SOCIAL MEDIA EXPORT
==================================================

Add optional export size:

Postcard
Instagram Square
Instagram Story
Facebook Post
WhatsApp Status

The postcard design should intelligently fit the selected ratio.

==================================================
17. RESPONSIVE DESIGN
==================================================

Desktop:
- Large postcard preview
- Editor controls beside/below it
- Spacious layout

Tablet:
- Responsive two-column or stacked layout

Mobile:
- Single-column
- Large postcard preview
- Easy touch controls
- Sticky download button at bottom when appropriate

Ensure:
- No horizontal overflow
- No broken cards
- No tiny text
- Buttons are easy to tap

==================================================
18. NAVIGATION
==================================================

Navbar:

💌 Vintage Postcard

Home
Postcards
Quotes
Vintage Gallery
Categories
Favorites

Right side:
“✨ Create Postcard”

Mobile:
Hamburger menu.

==================================================
19. FOOTER
==================================================

Footer:

💌 Vintage Postcard

“পুরনো দিনের অনুভূতি, আজকের ভালোবাসার জন্য।”

Links:
Home

Privacy Policy
Terms

Add copyright.

==================================================
20. ADMIN-FRIENDLY DATA STRUCTURE
==================================================

Structure the application so I can easily add:

100+ postcard templates
500+ romantic quotes
100+ vintage quote images

Use clean arrays/JSON/data files.

Example:

postcards = [
  {
    id: "vp001",
    title: "Rainy Love",
    category: "বৃষ্টি",
    image: "...",
    defaultQuote: "...",
    style: {...}
  }
]

quotes = [
  {
    id: "q001",
    text: "...",
    category: "রোমান্টিক"
  }
]

gallery = [
  {
    id: "g001",
    image: "...",
    category: "Vintage Love"
  }
]

Make adding new content extremely easy.

==================================================
21. PERFORMANCE
==================================================

Optimize the website for fast loading.

Use:
- Lazy loading
- Responsive images
- WebP where appropriate
- Code splitting where appropriate
- Efficient rendering
- Minimal unnecessary animations

Do not load every artwork at once.

==================================================
22. SEO
==================================================

Create SEO-friendly metadata.

Title:
“Vintage Postcard Generator – প্রেমের উক্তি দিয়ে সুন্দর পোস্টকার্ড তৈরি করুন”

Description:
“অনলাইনে তৈরি করুন সুন্দর Vintage Love Postcard। পছন্দের ডিজাইন ও প্রেমের উক্তি নির্বাচন করুন, নিজের লেখা যোগ করুন এবং HD পোস্টকার্ড ডাউনলোড করুন।”

Use semantic HTML.

Create SEO-friendly category pages.

==================================================
23. USER EXPERIENCE
==================================================

The website must be extremely easy to understand.

A first-time visitor should be able to create a postcard without instructions.

Ideal flow:

HOME
↓
CREATE POSTCARD
↓
SELECT DESIGN
↓
SELECT QUOTE / WRITE YOUR OWN
↓
CUSTOMIZE
↓
PREVIEW
↓
DOWNLOAD
↓
8-SECOND DOWNLOAD GATE
↓
HD DOWNLOAD

Do not add unnecessary complexity.

==================================================
24. IMPORTANT CONTENT RULE
==================================================

Do NOT make this website dependent on AI generation at runtime.

The artwork should be pre-generated/static assets.

I will create the vintage artwork separately and add the images later.

Therefore build a clean asset system such as:

/assets/postcards/
/assets/gallery/
/assets/fonts/

Use attractive placeholder/demo images if actual assets are unavailable.

==================================================
25. FINAL QUALITY
==================================================

The final website should look like a real premium product, not a basic demo.

Focus heavily on:
- beautiful typography
- elegant spacing
- realistic vintage postcard preview
- premium dark UI
- smooth transitions
- responsive layout
- easy customization
- fast download
- polished download gate

Avoid:
- excessive neon
- childish colors
- overly complicated editor
- unnecessary dashboards
- photo upload
- AI image upload/editing
- cluttered interface

The core product is:

“Choose a beautiful vintage postcard, choose or write a love quote, customize the text, and download it.”

Build the complete working application with all pages, components, data structures, responsive styling, postcard rendering/export and the 8-second sponsor download gate described above.

Make sure the application is functional, not just a visual mockup.
