// Extension: daily-focus-board
// Renders the daily focus board as a GHCP canvas, backed by a JSON state file
// that both the canvas UI and the AI partner read and write. All the real logic
// (server, state, mutations, recap) lives in board-core.mjs so it can be tested
// without the SDK; this file only wires the canvas/session lifecycle + actions.
