All rules for this repository live in rules.md — the single, tool-neutral source of
truth. This file is only a pointer so the rules stay identical no matter which agent reads them.
→ Read rules.md in full before doing anything. It covers repository layout, device
logs, branch/PR policy, copy & design standards, SOLID/architecture, platform abstraction, quality
gates, the testing doctrine, the push/review loop, and the on-device testing & verification playbook.
Do not add rules here. Add them to rules.md.
