Why this matters
Saul’s laugh-ethos becomes Robin’s survival philosophy — a clean character-defining seed planted in her debut backstory. (NB: distinct from the unrelated Foreshadowing/Pirate Laugh Before Execution Mythic Doctrine and the various ”…Laugh Debut” seeds — those are separate laugh-motif beats; this Saul doctrine is its own thing. Cross-link permitted, but keep distinct.) Links Nico Robin, Saul.
