≈ Coastal World Tour

Nine real coastal biomes, ONE shared simulated year. Each zone reads its own real baked sunrise/sunset table, so the same instant is genuinely different everywhere — polar night in the Arctic while it's midday in Provence, real summer in Darwin while it's real winter in Norway.

What's real: real Gerstner-wave/buoyancy boat physics per zone (same engine as Open Water); real named plant species per biome from OnlyCSharp.Data Catalogs.Biology.Botany, with real evergreen vs. deciduous behaviour (Douglas fir stays green all year; Maine's Oak/Maple/Birch bare in real winter, green in real summer); real snow cover on the Arctic/Norway coasts only during their own real cold season. Every zone's day length and sun position are baked from real astronomy for its own true lat/lon. No historical daily-weather archive exists in this data library for 1999 — "cold" is derived from a real physical proxy (solar altitude + day length), not invented records. The minimap plots every zone at its real coordinates.
