fix(mockup): Viradhya name, Tia portrait avatar, real photos in memories grid

- Baby name: Arjun → Viradhya (greeting + card name + img alt)
- Baby card avatar: 👶 emoji → tia-portrait.jpg (circle crop, object-top)
- Memories grid: emoji color blocks → real photos
    Slot 1: tia-portrait.jpg (First smile 😊)
    Slot 2: Unsplash baby photo (Bath time 🛁)
    Slot 3: family-illustration.jpg (With family 🌸)
    Slot 4: Unsplash baby photo (8 months! 🎉)
  Each card has dark gradient overlay so white caption is readable
