## About

Stockholm Archipelago Map is a single-page interactive map covering 16 islands across Sweden's largest archipelago, all reachable by public ferry from Stockholm. Each island is a clickable polygon that opens a popup with a short description, ferry information from Strömkajen, and a link to the corresponding guide on adayin.se. POI layers for beaches, restaurants, jetties and hotels can be toggled independently.

## Deep linking

The map supports URL parameters for embedding and sharing:

- `?island=<slug>` — pre-selects an island on load (highlights it, zooms to it, opens popup)
- `?layers=<comma-list>` — activates POI layers on load; valid values: `beaches`, `restaurants`, `hotels`, `jetties`

Parameters can be combined freely: `?island=grinda&layers=beaches,restaurants`
