2. CHECKS if meals are already ordered for next 2 weeks
3. Only orders if needed
4. Sends Telegram notification with status

Install dependencies:

Diet rules for selecting lunch:
1. NEVER select any dish containing pork (Schwein, Schweinefleisch, Schinken, Speck, Bacon, Wurst unless specified as chicken/beef)
2. PREFER simple dishes like:
   - Pasta dishes (Nudeln, Spaghetti, Penne, Makkaroni)
   - Rice dishes (Reis)
   - Chicken (Hähnchen, Huhn, Geflügel)
   - Fish sticks (Fischstäbchen)
   - Pizza
   - Schnitzel (only if chicken/turkey, NOT pork)
   - Pancakes (Pfannkuchen, Eierkuchen)
3. AVOID dishes with too many vegetables as main component
4. If multiple options available, choose the simpler/kid-friendlier option
5. German menu items are common - translate and apply rules accordingly

    Your task is to check and order school lunch for Fuji for the next two weeks.
    
    STEP 1 - LOGIN:
    1. Go to: {LOGIN_URL}
    2. Find the login form
    3. Enter customer number/ID: {CUSTOMER_ID}
    4. Enter password: {PASSWORD}
    5. Click login/submit button
    
    STEP 2 - CHECK EXISTING ORDERS:
    1. After login, navigate to the ordering/menu section
    2. Look at the next two weeks
    3. CHECK if meals are ALREADY ORDERED for each day
    4. Note which days already have orders and what meals are selected
    5. Note which days are MISSING orders (need to be ordered)
    
    STEP 3 - DETERMINE ACTION:
    - If ALL days for the next 2 weeks already have meals ordered:
      → Report "All meals already ordered" with the list of what's ordered
      → Skip to STEP 5 (do not order anything)
    
    - If SOME days are missing orders:
      → Report which days are already ordered
      → Proceed to STEP 4 to order the missing days
    
    STEP 4 - SELECT MEALS (only for days without orders):
    For each day that NEEDS ordering, select a meal following these diet rules:
    {DIET_PREFERENCES}
    
    After selecting, confirm/submit the order.
    
    STEP 5 - FINAL REPORT:
    Provide a clear summary with:
    
    STATUS: [ALREADY_ORDERED / NEWLY_ORDERED / PARTIAL_ORDER]
    
    ALREADY ORDERED (were already in the system):
    - List each date and meal that was already ordered
    
    NEWLY ORDERED (ordered during this session):
    - List each date and meal that was just ordered
    - Or "None" if everything was already ordered
    
    DAYS WITHOUT ORDERS:
    - List any days that couldn't be ordered (if any)
    - Or "None" if all days are covered
    
    IMPORTANT:
    - Be thorough when checking existing orders
    - Do NOT re-order days that already have meals selected
    - If unsure about a dish containing pork, skip it
