From 9029f1632a723f14ef5446adeb283f1b71e514c1 Mon Sep 17 00:00:00 2001 From: Julian Tabel Date: Sat, 14 Feb 2026 22:42:49 +0100 Subject: [PATCH] Add encounter condition support with rate display Add a `condition` column to RouteEncounter for time-of-day, weather, and season variants. Seed loader expands `conditions` dict into per-condition rows. EncounterModal shows condition filter tabs with per-condition encounter rates, and displays rates for all standard encounter methods (walk, surf, fishing, etc.).
