<!--
  Pointer file. Claude Code (CLAUDE.md) and Codex (AGENTS.md) each pick up
  their own filename when they boot in this repo. Keeping CLAUDE.md as a
  one-line `@AGENTS.md` reference means the operating manual lives in a
  single file (AGENTS.md) without either tool falling back to defaults.
  Do not duplicate content here, edit AGENTS.md.
