"""recipe-report — data + HTML helper for the weekly "Recipe Report" (/recipe-report skill).

Three subcommands; the /recipe-report agent runs them around its own review/classification:
  survey [DATE]            print structured JSON of the run + every recipe's open PRs + CI verdict
                           (DATE defaults to today UTC; reads the dated /upgrade-all summary if present)
  render SPEC.json OUT.html   render the agent's report spec -> a self-contained HTML page
  publish OUT.html DATE    copy the page to cc-ci:/var/lib/cc-ci-reports/week-DATE.html and regen index

The agent: `survey` -> review the data, write a SPEC (see SPEC SHAPE below) -> `render` -> `publish`.

SPEC SHAPE (the agent writes this JSON):
  {"date":"YYYY-MM-DD","subtitle":"Week of <human date>","headline":"one line",
   "needs_attention":[{"title":"...","body":"<plain text>","links":[{"text":"PR #4","url":"..."}]}],
   "routine":[ {same shape} ],
   "table":[{"recipe":"x","change":"a → b","status":"GREEN","ci":"level 8 ✓","ci_url":"...",
             "pr":"#4","pr_url":"...","notes":"..."}]}
PUBLIC PAGE — include only public-safe data (no secrets/tokens/raw logs).
