2. Safe Numeric Parsing - Replaced parseFloat/parseInt with safeParseFloat()/safeParseInt() that handle invalid inputs
3. Image URL Validation - Added isValidImageUrl() to prevent unsafe image sources (blocks javascript:, script tags)
4. Card/Bank Number Sanitization - Added sanitizeCardNumber() and sanitizeBankAccountNumber() to ensure only last 4 digits shown
5. Currency Symbol Validation - Added validation to prevent injection via currency symbols
6. TypeScript Interfaces - Converted classes to interfaces with proper type definitions
7. Development Logging - Console statements only execute in development mode via ngDevMode
8. Strict Equality - Changed == to === for all comparisons
9. Error Boundary - Component gracefully handles invalid/missing data
