# Milestone 1 Spec — Entry Enrichment
**Goal:** Every entry is richer out of the box — location name shown, weather auto-captured, photos in a proper gallery, hero image visible on the feed.
---
## User Stories
- As a traveler (Mischa), when I submit the post form, I want my current weather conditions auto-filled so I don't have to look them up manually.
- As a traveler, I want to type my city and country once and have it appear on the entry and in the feed card, so readers know where I am without reading the whole post.
- As a reader, when I scan the feed, I want to see a thumbnail photo and location for each entry so I can quickly get a sense of where Mischa is and whether to read the full entry.
- As a reader, when I open an entry, I want to see all uploaded photos in a gallery I can browse, not a wall of raw images.
- As a traveler, when I submit a form without photos, the entry should still display cleanly with no broken image placeholders.
---
## Feature Details
### 1.1 — Location Name Field on Post Form
**What:** Add two text fields to the post form: `location_city` and `location_country`.
**Behavior:**
- Both are optional (GPS coordinates are also optional)
- Placeholder text: "e.g. Kyoto" and "e.g. Japan"
- Displayed below the lat/lng fields
- On submit, stored in entry frontmatter as `location_city` and `location_country`
- On the form, shown as a single labeled group "Location Name" with two side-by-side inputs on desktop, stacked on mobile
**Edge cases:**
- If left blank: entry shows no location badge. No error, no broken UI.
- Long city names (e.g. "Ulaanbaatar") must not overflow card layout.
- Special characters (accents, non-Latin) must render correctly.
**Mobile behavior:** Both fields full-width, stacked, 44px min touch targets.
---
### 1.2 — Weather Auto-Fetch on Post Form
**What:** A "Get Weather" button on the post form that calls the Open-Meteo free API (no API key) using the lat/lng already entered, and fills hidden weather fields.
**Fields to fetch and store:**
- `weather_temp_c` — temperature in Celsius (integer)
- `weather_desc` — short description: one of: Sunny, Partly cloudy, Cloudy, Foggy, Drizzle, Rain, Snow, Thunderstorm (derived from WMO weather code)
**WMO code mapping (Open-Meteo uses WMO codes):**
- 0 → Sunny
- 1,2 → Partly cloudy
- 3 → Cloudy
- 45,48 → Foggy
- 51,53,55,56,57 → Drizzle
- 61,63,65,66,67,80,81,82 → Rain
- 71,73,75,77,85,86 → Snow
- 95,96,99 → Thunderstorm
**API call:**
```
https://api.open-meteo.com/v1/forecast?latitude={lat}&longitude={lng}&current=temperature_2m,weather_code&temperature_unit=celsius
```
**UX flow:**
1. User fills in lat/lng (manually or via "Get Location" button)
2. User taps "Get Weather" button
3. Button shows "Fetching…" while loading
4. On success: fills temp and desc fields (visible, editable text inputs)
5. On failure (no network, no lat/lng): shows inline error "Could not fetch weather — enter manually"
**Edge cases:**
- If lat/lng not filled when button tapped: show inline error "Enter coordinates first"
- Weather fields are always editable manually (auto-fill is a convenience, not mandatory)
- If weather fields left blank: entry shows no weather badge. No broken UI.
- Open-Meteo returns current conditions, not historical — this is fine for posting in real time
**Mobile behavior:** "Get Weather" button is full-width, 44px height, placed immediately below the lat/lng + location name fields.
---
### 1.3 — Weather Display on Entry Page
**What:** If `weather_temp_c` or `weather_desc` is present in frontmatter, display a weather badge on the entry page.
**Display format:** `☀️ Sunny · 28°C` (icon + description + temperature)
- Icon chosen from a small set based on `weather_desc`:
- Sunny → ☀️
- Partly cloudy → ⛅
- Cloudy → ☁️
- Foggy → 🌫️
- Drizzle → 🌦️
- Rain → 🌧️
- Snow → ❄️
- Thunderstorm → ⛈️
**Placement:** In the entry header, between the date and the body text. Same line as GPS coordinates if those are shown.
**Edge cases:**
- Only temp, no desc → show temp only
- Only desc, no temp → show desc only
- Neither → hide weather section entirely
- Temperature should always be integer (round if float)
---
### 1.4 — Location Badge on Feed Cards and Entry Page
**What:** Display `location_city, location_country` as a small badge on tracker feed cards and at the top of entry pages.
**Feed card:** Below the date, above the excerpt. Format: `📍 Kyoto, Japan`
**Entry page:** In the header below the date, above the content. Format: `📍 Kyoto, Japan`
**Edge cases:**
- Only city, no country → `📍 Kyoto`
- Only country, no city → `📍 Japan`
- Neither → location badge hidden entirely
- Long location names: truncate with ellipsis at 30 chars on cards (full text on entry page)
---
### 1.5 — Photo Gallery on Entry Page
**What:** Photos uploaded to an entry should display in a responsive grid gallery with lightbox (click to enlarge).
**Implementation approach:** Use Grav's native media collection for the entry page. Each `.entry` folder contains its photos. Render them in a grid in `entry.html.twig`. Use a minimal vanilla JS lightbox — no external framework.
**Gallery behavior:**
- Photos displayed in a 2-column grid on mobile, 3-column on desktop
- Each thumbnail is square-cropped, 150px on mobile
- Clicking/tapping a thumbnail opens a lightbox overlay
- Lightbox: dark overlay, full-size image centered, tap/click outside or press Escape to close
- Left/right navigation arrows in lightbox (swipe on mobile)
- No captions needed for v1
**Edge cases:**
- 0 photos: gallery section hidden entirely
- 1 photo: still uses grid (single item), lightbox works
- Many photos (>10): gallery still renders (no hard limit on display)
- Non-image files in the media folder: skip them (only render jpg, jpeg, png, webp, gif)
---
### 1.6 — Hero Image on Tracker Feed Cards
**What:** If an entry has photos, the first photo (or the one named in `hero_image` frontmatter) appears as a thumbnail on the tracker feed card.
**Implementation:** In `tracker.html.twig`, for each entry:
1. If `entry.header.hero_image` is set, use `entry.media[entry.header.hero_image]`
2. Else, use the first image in `entry.media` sorted by name
3. Render as a 16:9 aspect-ratio thumbnail, full width of card, above the title
**Edge cases:**
- No photos: card shows no image, just text. No broken `<img>` tag.
- `hero_image` set but file missing: fall back to first media file, or no image
- Very tall/wide images: CSS `object-fit: cover` maintains card aspect ratio
---
## Out of Scope (Milestone 1)
- Map features (Milestone 2)
- Statistics page (Milestone 3)
- Video support
- Comments or reactions
- Automated reverse geocoding (city name comes from form input, not auto-detected)
- Altitude display (data may not be present)
- Historical weather (Open-Meteo current endpoint only)
---
## Acceptance Criteria
1. Post form has `location_city` and `location_country` fields that save to entry frontmatter
2. Post form has "Get Weather" button that fills `weather_temp_c` and `weather_desc` via Open-Meteo when lat/lng are provided
3. Entry page shows weather badge when weather fields are present; hidden when absent
4. Entry page shows location badge `📍 City, Country` when location fields are present; hidden when absent
5. Tracker feed card shows location badge when present
6. Tracker feed card shows a hero image when photos exist for an entry
7. Entry page shows a 2-col (mobile) / 3-col (desktop) photo grid
8. Clicking any photo opens a full-screen lightbox with prev/next navigation
9. Pressing Escape or clicking outside lightbox closes it
10. All fields are optional — empty values produce no broken UI elements
11. All interactive elements meet 44px minimum touch target on mobile
12. Form submits correctly with all new fields populated or all blank
---
## Design Notes
- Weather and location badges should be subtle — small text, muted color, not the visual focus
- Use emoji icons for weather — universal, no icon font dependency
- Gallery grid: `gap: 4px` between thumbs, no borders, square crops
- Lightbox: `background: rgba(0,0,0,0.92)`, image centered with `max-height: 90vh`
- Feed card image: `aspect-ratio: 16/9`, `object-fit: cover`, rounded top corners matching card

# Milestone 2 Spec — Interactive Map
**Goal:** A `/map` page shows all entries as markers on an interactive Leaflet.js map, connected by a chronological route line, with popups linking to entries.
---
## User Stories
- As a reader, I want to see a world map showing where Mischa has been so I can understand the journey at a glance without reading every entry.
- As a reader, I want to click a map marker and see the entry date, title, and a thumbnail — and be able to click through to the full entry.
- As a reader on mobile, I want to pan and pinch-zoom the map with my fingers without the page scrolling underneath.
- As a traveler (Mischa), I want the map to automatically include every entry that has lat/lng data — I should not need to do any manual map maintenance.
- As a reader, I want the map to show the route line connecting stops in the order they were visited, so the journey makes narrative sense.
---
## Feature Details
### 2.1 — Map Page
**Route:** `/map`
**Template:** `map.html.twig` — extends `partials/base.html.twig`
**Page file:** `user/pages/03.map/map.md`
**Content:**
- Full-viewport-height map container below the site header
- Leaflet.js loaded from CDN (jsDelivr): `https://cdn.jsdelivr.net/npm/leaflet@1.9.4/dist/leaflet.min.js`
- Leaflet CSS from same CDN
- Tile layer: OpenStreetMap (free, no API key): `https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png`
- Attribution: "© OpenStreetMap contributors"
**Map initialization:**
- Default zoom: auto-fit to bounds of all markers (use `map.fitBounds()`)
- If no entries with GPS data: show world view, zoom 2, centered at 0,0 with a message "No locations yet"
- Min zoom: 2, Max zoom: 18
---
### 2.2 — Entry Data Serialization
**How entries reach the map JS:**
In `map.html.twig`, Grav's Twig will iterate all published entries under `/tracker` and serialize them to a JSON array embedded in a `<script>` tag:
```js
var ENTRIES = [
{
"lat": 48.8566,
"lng": 2.3522,
"title": "Paris morning",
"date": "2026-06-18",
"url": "/tracker/2026-06-18",
"hero": "/path/to/thumb.jpg" // null if no photo
},
...
];
```
**Only entries with valid lat AND lng are included** (skip entries where either is empty/null).
Entries sorted ascending by date (oldest first) so the route line is drawn in travel order.
---
### 2.3 — Route Polyline
**What:** A colored line drawn between entry markers in chronological order.
**Style:**
- Color: `#0066cc` (brand blue, matches existing CSS)
- Weight: 3px
- Opacity: 0.7
- No arrow heads for v1
**Behavior:**
- Line drawn between consecutive entries (by date) that have valid GPS
- If only 1 entry: no line (just a single marker)
- If two consecutive entries are very far apart (>5000km): line still drawn — it's a flight, expected
---
### 2.4 — Entry Markers
**What:** One circular marker per entry with GPS coordinates.
**Marker design:**
- Custom circular marker (not default Leaflet teardrop)
- Color: `#0066cc` fill, white border, 2px border
- Size: 12px diameter on mobile, 14px on desktop
- Most recent entry: larger (18px) and brighter color to indicate "current location"
**Popup on click/tap:**
```
[thumbnail if available — 120px wide, 80px tall, cover cropped]
📅 18 June 2026
Paris morning
[Read entry →]
```
- Popup width: 180px max
- "Read entry →" links to the entry page
- Tapping outside popup closes it
**Edge cases:**
- Two entries at the same lat/lng: Leaflet clusters or offsets them slightly (use small offset to prevent exact overlap — just add 0.0001° offset per duplicate)
- Entry with GPS but no photo: popup shows no image, just date + title + link
---
### 2.5 — Mobile Map UX
**Problem:** On mobile, a map inside a scrollable page creates a scroll-trap (finger intended for page scroll gets captured by map pan).
**Solution:**
- Map container is `height: calc(100vh - 60px)` (full viewport minus header)
- Map is the primary content of the page — no scroll needed
- `touch-action: none` on the map container prevents page scroll interference
- Leaflet handles touch pan/zoom natively
---
### 2.6 — Navigation Link
**What:** "Map" link added to the site header navigation.
**Where:** `partials/base.html.twig` nav section — add `<a href="{{ base_url_absolute }}/map">Map</a>`
---
## Out of Scope (Milestone 2)
- Filtering markers by date range
- Clustering markers at low zoom levels
- Heatmap or density visualization
- Showing the route on the tracker feed page (Milestone 4)
- Showing elevation profile
- Country highlight/fill on the map
- Offline map tiles
---
## Acceptance Criteria
1. `/map` page exists and returns HTTP 200
2. Page renders a full-height interactive map
3. All published entries with valid lat/lng appear as markers
4. Markers are connected by a route line in date order
5. Clicking/tapping a marker shows a popup with date, title, and link
6. Popup link navigates to the correct entry page
7. Most recent entry marker is visually distinct (larger/brighter)
8. If no entries have GPS: map renders at world zoom with "No locations yet" message
9. Map is pannable and zoomable by touch on mobile
10. "Map" link appears in site navigation and routes to `/map`
11. Map auto-fits to show all markers on page load
12. Entries without lat/lng are silently excluded (no JS errors)
---
## Design Notes
- Map tile layer: OpenStreetMap default tiles. Clean, recognizable, free.
- Keep the Grav site header visible above the map — don't go full-screen (users need the nav)
- Popup design: minimal. White background, slight box-shadow, 8px border-radius
- Do not use any Leaflet plugins beyond the core library — keep the dependency footprint tiny
- The map page should load fast: Leaflet is ~42KB gzipped. Tile images load progressively. No blocking.

# Milestone 3 Spec — Statistics Page
**Goal:** A `/stats` page showing key trip numbers: days on the road, entries posted, countries visited, and approximate distance traveled.
---
## User Stories
- As a reader, I want to see a quick summary of how far Mischa has traveled and how many countries they've visited, without having to read every entry.
- As a traveler (Mischa), I want to see my own trip stats at a glance — a satisfying progress indicator while traveling.
- As a reader, I want stats that update automatically as new entries are posted — no manual maintenance.
---
## Feature Details
### 3.1 — Stats Page
**Route:** `/stats`
**Template:** `stats.html.twig` — extends `partials/base.html.twig`
**Page file:** `user/pages/04.stats/stats.md`
**Computed in Twig** (server-side, from published entries under `/tracker`):
---
### 3.2 — Stat: Days on the Road
**Definition:** Number of calendar days from the date of the first published entry to today.
**Formula (Twig):**
```twig
{% set first_entry = entries|first %}
{% set days = (now.timestamp - first_entry.date|date('U'))|round / 86400 %}
{% set days_on_road = [days|round(0, 'floor'), 0]|max %}
```
**Display:** `42 days on the road`
**Edge cases:**
- No entries: show `0 days on the road` or `Trip not started yet`
- Only one entry (today): show `1 day on the road`
---
### 3.3 — Stat: Entries Posted
**Definition:** Count of all published entries under `/tracker`.
**Display:** `17 entries posted`
**Edge cases:**
- 0 entries: `0 entries posted`
- 1 entry: `1 entry posted` (singular)
---
### 3.4 — Stat: Countries Visited
**Definition:** Unique values of `location_country` across all published entries, non-empty.
**Display:** Count + list
```
6 countries visited
Japan · South Korea · Mongolia · Russia · Finland · Estonia
```
**Edge cases:**
- No entries have `location_country`: show `Countries: —`
- Some entries missing `location_country`: count only those that have it; note "(based on X of Y entries)"
- Duplicate country names are de-duplicated (case-insensitive)
---
### 3.5 — Stat: Approximate Distance Traveled
**Definition:** Sum of great-circle (haversine) distances between consecutive entries that have valid lat/lng, in ascending date order.
**Implementation:** Computed in Twig using a haversine formula macro.
**Haversine in Twig:**
```twig
{% macro haversine(lat1, lng1, lat2, lng2) %}
{% set R = 6371 %}
{% set dLat = ((lat2 - lat1) * 3.14159265 / 180) %}
{% set dLng = ((lng2 - lng1) * 3.14159265 / 180) %}
{% set a = (dLat/2)|sin * (dLat/2)|sin + (lat1 * 3.14159265 / 180)|cos * (lat2 * 3.14159265 / 180)|cos * (dLng/2)|sin * (dLng/2)|sin %}
{% set c = 2 * a|sqrt|asin %}
{{ (R * c)|round }}
{% endmacro %}
```
Note: Twig does not have `sin`/`cos`/`asin`/`sqrt` built-in. Use a JavaScript-side calculation instead:
**Implementation:** Embed the entry GPS data as JSON in the template (same pattern as Milestone 2), compute distance in vanilla JS, and write the result into the DOM on page load.
```js
function haversine(lat1, lng1, lat2, lng2) {
var R = 6371;
var dLat = (lat2 - lat1) * Math.PI / 180;
var dLng = (lng2 - lng1) * Math.PI / 180;
var a = Math.sin(dLat/2)**2 + Math.cos(lat1*Math.PI/180) * Math.cos(lat2*Math.PI/180) * Math.sin(dLng/2)**2;
return R * 2 * Math.asin(Math.sqrt(a));
}
var total = 0;
for (var i = 1; i < GPS_POINTS.length; i++) {
total += haversine(GPS_POINTS[i-1][0], GPS_POINTS[i-1][1], GPS_POINTS[i][0], GPS_POINTS[i][1]);
}
document.getElementById('stat-distance').textContent = Math.round(total).toLocaleString() + ' km';
```
**Display:** `~3,400 km traveled`
**Edge cases:**
- 0 or 1 GPS points: `Distance: —`
- Very large numbers (trans-continental trip): use thousands separator: `12,400 km`
- Disclaimer note: "approximate — based on straight lines between entry locations"
---
### 3.6 — Visual Layout
**Layout:** 4 large stat blocks in a 2×2 grid on desktop, stacked on mobile.
Each block:
```
┌─────────────────┐
│ 42 │
│ days on road │
└─────────────────┘
```
- Number: large (3rem), bold, brand blue
- Label: small (0.85rem), muted grey
- Background: white, 1px border, 8px radius, subtle shadow
- Mobile: 2-col grid (2 stats per row)
Below the grid: list of countries visited (plain text, centered, muted).
---
### 3.7 — Navigation Link
Add "Stats" to the site navigation in `partials/base.html.twig`.
---
## Out of Scope (Milestone 3)
- Charts or graphs (bar charts, line graphs, etc.)
- World map with highlighted countries (that's a visual enhancement, deferred)
- Per-country breakdown (km in each country, days in each country)
- Speed statistics (km/day average)
- Elevation statistics
- Historical comparison (vs. last trip)
---
## Acceptance Criteria
1. `/stats` page exists and returns HTTP 200
2. "Days on the road" shows correct count from first entry date to today
3. "Entries posted" shows count of published entries
4. "Countries visited" shows correct count + list of unique non-empty `location_country` values
5. "Distance traveled" shows km sum of haversine distances between consecutive GPS entries
6. All four stats display in a 2×2 grid on desktop
7. On mobile (375px), stats stack into a 2-column responsive grid
8. Stats auto-update when new entries are published (no manual maintenance)
9. If no entries: all stats show 0 or `—`, no JS errors
10. "Stats" link in navigation routes to `/stats`
---
## Design Notes
- Stats should feel like a dashboard, not a table — big numbers, small labels
- Do not use any external charting library for v1
- Countries list below the grid: inline, separated by `·`, muted grey
- The "approximate" disclaimer for distance should be in small print below the distance stat

# Milestone 4 Spec — Mini-Map on Tracker Feed
**Goal:** Embed a compact interactive map above the entry feed on the tracker page, showing recent entry positions and the current location, giving readers immediate spatial context.
---
## User Stories
- As a reader landing on the tracker feed, I want to immediately see where Mischa currently is without having to navigate to the full map page.
- As a reader, I want to click a marker on the mini-map and jump to that entry.
- As a traveler (Mischa), I want the feed page to feel like a live travel dashboard, not just a blog list.
---
## Feature Details
### 4.1 — Mini-Map Placement
**Where:** At the top of `tracker.html.twig`, before the entry card list.
**Height:** 240px on mobile, 320px on desktop.
**Width:** Full width of content column (max 680px).
**Tile layer:** Same OpenStreetMap tiles as Milestone 2.
**No duplicate Leaflet load:** Leaflet is already loaded on the map page; on the tracker page, load it only if needed. Check with `if (typeof L === 'undefined')` before initializing. (In practice, the CSS and JS are loaded unconditionally from the same CDN — caching handles it.)
---
### 4.2 — What's Shown
- **All entries with GPS** shown as small markers (not just recent 10 — the map auto-fits to bounds)
- **Route line** connecting them in chronological order (same style as Milestone 2)
- **Most recent marker** highlighted (larger, brighter)
- **No popups by default** — tapping a marker links directly to the entry (no popup intermediary for the mini-map, keeps it fast)
- Map auto-fits bounds to all markers; if only 1 marker, zoom to 10
---
### 4.3 — Interaction
- Tap/click marker → navigate to entry URL directly
- Map is pannable and zoomable (same touch handling as M2)
- "View full map →" link below the mini-map → navigates to `/map`
---
### 4.4 — Entry Data
Same JSON serialization as Milestone 2 (embed `TRACKER_ENTRIES` in the Twig template). This can reuse the same data variable name if both map and tracker pages use the same template pattern.
---
### 4.5 — Empty State
If no entries have GPS coordinates:
- Mini-map hidden entirely (don't show an empty world map on the feed page)
- Entry list still shows normally
---
## Out of Scope (Milestone 4)
- Clustering markers at low zoom
- Filtering by date
- Satellite/terrain tile layers
- Search on the mini-map
---
## Acceptance Criteria
1. Mini-map appears above entry cards on the tracker feed page
2. All entries with valid lat/lng appear as markers on the mini-map
3. Route line connects markers in date order
4. Most recent marker is visually distinct
5. Clicking/tapping a marker navigates directly to that entry
6. "View full map →" link appears below the mini-map and routes to `/map`
7. If no entries have GPS, mini-map is hidden and entry list shows normally
8. Mini-map is pannable and zoomable by touch on mobile
9. Mini-map does not block page scrolling on mobile (map is fixed height, not full-screen)
---
## Design Notes
- Mini-map border-radius should match the card design (8px)
- Light 1px border or subtle shadow to separate from content
- "View full map →" in small muted text, right-aligned
- Keep the mini-map lightweight: same Leaflet instance, no additional plugins
