Output format for ad-hoc recommendation:

```
Task: "implement OAuth login for the API"
Route: B (Standard)

  Primary:    Codex Sonnet  [quota: <Codex>% — OK]
  Secondary:  Codex          [quota: <CODEX>%  — OK]

  Rationale: Standard feature implementation with moderate complexity.
             Sonnet provides quality output within quota headroom.
             Codex is secondary for focused function-level generation.
