Import / export

Export (board-import-export.js)

Payload:

{
  "app": "weekly-planner",
  "version": 2,
  "exportedAt": "...",
  "boards": [ /* normalized boards + events */ ]
}

exportFilename() uses a Korean date-based name. downloadJson creates a Blob URL.

Import

parseImportText → buildImportTransactions → Instant txs via useBoardLifecycle. Accepts:

• Raw event array
• Object with boards
• Object with events

Everything normalizes through eventFields / boardFields. Activates the first imported board.

Legacy migration (legacy.js)

Keys: weekly-planner.v2, then weekly-planner.v1.

• v2 boards migrate when present
• v1 raw events become one board

Runs inside ensureWorkspace only when the user has zero accessible boards. Boot toast when migrated.
