Two new specs:
- 2026-05-24-zacus-hub-app.md — architecture, sprints, auth,
open decisions for the SwiftUI hub app + gateway.
- 2026-05-24-firmware-scenario-hotload.md — firmware Phase 2
plan for /game/scenario + ESP-NOW mesh relay (the master
side has shipped on the submodule; the relay + peer
receivers + scenario_engine_reload remain to do).
Submodule ESP32_ZACUS bumped to d220d94 on feat/idf-migration
(POST /game/scenario hot-load on master, scenario_server.c on
BOX-3, ota_server max_uri_handlers 8->16, sdkconfig.qemu).
