"""Phase 3 U4 — dashboard YunoHost-style grid + per-recipe history (pure-render + helpers).

The dashboard reads a Drone admin token at import; point DRONE_TOKEN_FILE at a temp file so the
module imports without the real secret. All tests here are pure (no network): they exercise the
rendering + results.json projection, asserting the grid/history mirror the artifact and never present
a run greener than its data (R5 / cardinal guardrail)."""
