Captures everything needed to redeploy the two-display clock (hour on I2C 0x61, minute on I2C 0x63) on a fresh Pi: - Both systemd units (matrix0x61.service, matrix0x63.service) - Deployed Pimoroni script tree, including the local %I (12-hour) clock customization - Vendored upstream sources (ltp305-python, breakout-garden) so restore is fully offline-capable - Boot config snippet enabling I2C - install.sh that wires it all back up idempotently - Inventory doc cross-referencing every live-system path Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
