From 13a3d16ffc88845d7bc65fb0778da9aaff53b653 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Sat, 2 May 2026 11:31:42 +0900 Subject: feat(auth): clear local IndexedDB and sync state on explicit logout Wipe Dexie databases (main + CRDT sync state) and reset the sync queue when the user explicitly logs out so the next account on the same device starts from a clean local store. Session expiry deliberately keeps local data intact so a returning user finds their offline work waiting.
