## Overview

Map Journal is a single-page web application for documenting and visualizing travel experiences. Users log trips by country, pinning cities, dates, transport modes, and photos, and then explore their journey on an interactive world map or a timeline view.

### How It Works

1. **Sign in** with a Google account.
2. **Select your home country** — it is automatically marked as visited on the map.
3. **Add journal entries** via a multi-step form:
   - **Step 1** — Choose country, cities, arrival date, days stayed, trip type (solo/friends/family), and transport (flight/train/bus/car/ship/walk).
   - **Step 2** — Upload photos (stored in Firebase Storage).
   - **Step 3** — Answer three random reflective questions about the trip (e.g., *"What was the most unexpected thing that happened?"*).
4. **Edit entries** through the same form, pre-filled with existing data.
5. **View your journey** on a D3-powered world map where visited countries are highlighted and animated flight paths connect entries in chronological order.
6. **Browse a timeline** sorted by date, country, or recency.
7. **Share** a generated summary card to show off your stats.

    ├── TopBar.svelte
    ├── CountryPicker.svelte
    ├── WorldMap.svelte

        ├── NewEntryForm.svelte
        │   ├── StepNavbar.svelte

        │   └── ...
        ├── ShareCard.svelte
        └── SharePreview.svelte
```

### Data Flow

```
Firebase Auth          ──→  userStore.svelte.js  ──→  Layout (auth guard)
Firebase Firestore     ──→  entriesStore.svelte.js ──→  Timeline, Map (via $state/$derived)
Firebase Storage       ──→  PhotoEditor.svelte (upload)
selection.svelte.js    ──→  visited set (derived from entries + home country)
```

### Key Patterns

- **Svelte 5 runes** — `$state`, `$derived`, `$effect`, `$bindable`, `$props` replace the old Svelte store/reactivity model.
- **$bindable props** — `TripBasicInfo` uses `$bindable()` for two-way binding with its parent form, keeping form state in the parent while delegating UI rendering.
- **Firebase listeners** — `entriesStore` uses `onSnapshot` for real-time Firestore sync; `userStore` uses `onAuthStateChanged`.
- **D3.js** — `WorldMap` renders a GeoJSON world map with centered zoom via `d3-geo`; `JourneyView` animates SVG flight paths.
- **No framework router** — the app uses a simple `mode` state variable (`'map' | 'journal'`) in `App.svelte` to switch between views.

## Known Bugs & Limitations

- **Photo Editor** — The `.add-btn` CSS class is unused (replaced by `.add-cell`); leftover from refactoring.
- **ShareCard** — Several CSS classes (`.stat-grid`, `.stat-box`, `.cont-section`, etc.) are defined but unused in the template; they were intended for a statistics section that was not implemented.
- **Photo upload error** — If Firebase Storage upload fails, the error is displayed but the photo grid does not automatically roll back the failed entry.
- **State_referenced_locally warnings** — `EditForm.svelte` initializes `$state` variables from `$props()` at declaration; this is intentional (one‑time init on edit mode) but Svelte 5's analyzer emits warnings.
- **A11y warnings** — Some form labels lack `for`/`id` associations (transport pills, trip‑type toggles); these are visual‑only controls where the label wraps the input, which is functional but not strictly valid per WAI‑ARIA.
