/**
 * Renders the small markdown subset that `formatEvent` emits into ANSI-styled
 * terminal text — the stdout analogue of `renderTelegramHtml`. The semantic
 * event formatter stays surface-agnostic (it speaks markdown); each sink renders
 * that markdown for its own surface (Telegram → HTML, stdout → ANSI/plain).
 *
 * When `colour` is false (a non-TTY, NO_COLOR, or --plain), the markup is
 * STRIPPED to clean plain text rather than styled, so a piped log carries no
 * escape codes and no leaked `**` asterisks. Pure (no I/O) so it is unit-tested
 * directly.
