✨ Features

• 🏩 Hotel Cards: Each hotel displays name, city, rating, price per night, amenities, and availability status in a glassmorphism card.
• 💳 Card Validation: Credit card details (number, expiry, holder, CVC) are validated against a CSV dataset before any booking is confirmed.
• 🔐 2-Step Authentication: SecureCreditCard adds a password check on top of standard validation — no booking without both passing.
• 🧖 Spa Upgrade: Eligible hotels offer an optional VIP Spa add-on, handled via the SpaHotel subclass.
• 📄 PDF Ticket Generation: A formatted A4 reservation statement is generated with fpdf2 and offered as a download after booking.
• 🎨 Premium Dark UI: Animated gradient background, glassmorphism cards, hover effects — all injected via styles.py.

🧠 Architecture

The app is split into focused classes, keeping business logic separate from the UI layer.

Hotel & SpaHotel — Inheritance

SpaHotel extends Hotel with spa booking functionality — demonstrating OOP inheritance cleanly:

class SpaHotel(Hotel):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.spa_included = False

    def book_spa(self):
        self.spa_included = True

CreditCard & SecureCreditCard — Two-Layer Validation

Standard card data is validated against cards.csv. The secure subclass adds a password layer checked against card-security.csv:

class SecureCreditCard(CreditCard):
    def authenticate(self, given_password, df_security_dict):
        if self.number in df_security_dict:
            return df_security_dict[self.number] == given_password
        return False

BaseTicket & ReservationTicket — Abstract Base Class

BaseTicket is an ABC that handles all PDF layout logic. ReservationTicket only needs to implement generate_text() — keeping the PDF generation reusable:

class BaseTicket(ABC):
    @abstractmethod
    def generate_text(self) -> str:
        pass

    def generate_pdf(self, filename="ticket.pdf"):
        # Full A4 PDF layout with header, table, totals, footer...
