[LEGEND] CONTEXT_DOC = A Markdown doc written as `[LEGEND]` then `[CONTENT]`. [CONTENT] Doc format (mandatory for every [CONTEXT_DOC]): - Repo-root `AGENTS.md` and repo-root `README.md` are freeform Markdown. - Every other `.md` MUST be a context doc: - First non-empty line is `[LEGEND]`. - Then a `[CONTENT]` block. Token rules: - Define shared meanings in `LEGEND.md` as `TOKEN = Meaning`. - Define doc-specific meanings in the doc’s own `[LEGEND]`. - Do not shadow: a doc MUST NOT redefine a global token locally ([NO_SHADOWING]). - Use tokens in content via `[TOKEN]` (optionally `[TOKEN|LEGEND.md]`).
