The HTML comment at the top was aimed at maintainers opening the file,
but it's loaded verbatim into every agent's system prompt via the
`.claude-shared.md` import. Agents don't need the meta-explanation of
where the file is mounted or how identity gets injected — it's just
context-budget drag. Move the maintainer guidance out of the agent's
view.
