/**
 * The run's console voice, in layers the eye can separate:
 *
 *   ▸ narration   — what the ALGORITHM is doing right now (bold magenta):
 *                   phase openings, commits, barriers. The line to read
 *                   when skimming.
 *   session text  — the model's own human-readable sentences (cyan): the
 *                   signal inside a session.
 *   tool lines    — every tool call a session makes (dim): proof of life,
 *                   deliberately faded so it never competes with the text.
 *   prompts       — the full prompt handed to a session (dim, ┃-ruled):
 *                   printed verbatim so a run is auditable, faded so it
 *                   reads as reference material, not narration.
 *   commands      — catalog commands as they run ($-prefixed, dim).
 *
 * Colors follow the terminal's rules: disabled when stdout is not a TTY
 * or NO_COLOR is set (https://no-color.org/), so piped logs stay clean.
