+# Experimental Branch Summary
+
+*Branch: `experimental-polar-steps`. Ready for morning review.*
+
+---
+
+## What Was Done
+
+This branch researched Polarsteps and FindPenguins, distilled their best ideas for a solo travel blog on Grav CMS, planned four milestones, and implemented all four.
+
+---
+
+## What Was Built
+
+### Milestone 1 — Entry Enrichment
+- **Location badge** (`📍 City, Country`) on entry page and tracker feed cards
+- **Weather badge** (`⛅ Partly cloudy · 19°C`) on entry page header
+- **"Get Weather" button** on post form — auto-fetches via Open-Meteo (free, no key)
+- **Photo gallery** on entry pages — 2-col/3-col grid with full lightbox
+- **Hero image** on feed cards — falls back to first photo if no hero_image set
+- New post form fields: City, Country, weather auto-fill
+
+### Milestone 2 — Interactive Map (`/map`)
+- Leaflet.js with OpenStreetMap tiles
+- Marker per entry with GPS, route polyline in date order
+- Most recent entry highlighted
+- Click marker → popup with date, title, link to entry
+- Full-height map, mobile touch-friendly
+
+### Milestone 3 — Statistics Page (`/stats`)
+- Days on the road, entries posted, countries visited, distance traveled
+- Auto-updates as new entries are posted
+
+### Milestone 4 — Mini-map on Tracker Feed
+- Compact map above the entry list on /tracker
+- Tap marker → navigates to that entry
+- Hidden when no entries have GPS
+
+---
+
+## Navigation
+Three links in site header: **Journal · Map · Stats**
+
+---
+
+## Manual Verification Required on Mobile
+
+1. Upload photos → verify gallery grid + lightbox works
+2. Upload photo → verify hero image on feed card
+3. Open /post logged in → Get Location + Get Weather buttons work end-to-end
+4. Submit full entry → verify all badges appear
+5. Open /map on phone → pinch zoom (no page scroll behind map)
+6. Open /tracker → tap mini-map marker → navigates to entry
+7. Check browser console → no JS errors
+
+---
+
+## What Was Skipped
+Background GPS tracking, social features, video reels, 3D flyover, printed books, AI itinerary builder — all require native apps or don't suit a solo personal blog. Full reasoning in `docs/pm-analysis.md`.
