v1.4.7 — local-liaison playbook set

Bilingual EN/JA playbooks for the three trainable liaison scenarios: deploy an APK, morning status→dashboard, EOD shutdown/reboot. All open with a Red/Blue show-set gate, lead with the show SSID, keep on-screen text English. deploy: wildcarded APK path, real ~25min/no-progress note. Docs only — ./update.sh to get them.
