Add Python web scraper for NJC travel rates with currency extraction
- Implemented Python scraper using BeautifulSoup and pandas to automatically collect travel rates from official NJC website - Added currency extraction from table titles (supports EUR, USD, AUD, CAD, ARS, etc.) - Added country extraction from table titles for international rates - Flatten pandas MultiIndex columns for cleaner data structure - Default to CAD for domestic Canadian sources (accommodations and domestic tables) - Created SQLite database schema (raw_tables, rate_entries, exchange_rates, accommodations) - Successfully scraped 92 tables with 17,205 rate entries covering 25 international cities - Added migration script to convert scraped data to Node.js database format - Updated .gitignore for Python files (.venv/, __pycache__, *.pyc, *.sqlite3) - Fixed city validation and currency conversion in main app - Added comprehensive debug and verification scripts This replaces manual JSON maintenance with automated data collection from official government source.

## 🎓 Usage Examples
|
||||
|
||||
### Auto-Save
|
||||
```
|
||||
User starts filling form → Auto-saves every 2s → Browser crashes
|
||||
User returns → Prompt: "Restore data from [time]?" → Click Yes → Data restored!
|
||||
```
|
||||
|
||||
### Caching
|
||||
```
|
||||
User 1 searches YOW→YVR on Feb 15 → API call (500ms) → Cached
|
||||
User 2 searches YOW→YVR on Feb 15 → Cache hit! (25ms) → 20x faster!
|
||||
```
|
||||
|
||||
### Trip History
|
||||
```
|
||||
User completes estimate → Auto-saved to history
|
||||
User presses Ctrl+H → Sees all 20 recent trips
|
||||
User clicks trip → Form populated instantly
|
||||
```
|
||||
|
||||
### Dark Mode
|
||||
```
|
||||
User clicks 🌙 → Dark mode enabled → Preference saved
|
||||
User returns tomorrow → Still in dark mode → Consistent experience
