# Quest chain 3 (D29/D33): activated on the day-start after the carrot-quest
# completes, completes when the mayor dialogue is finished (dialogue-end with
# the mayor dialogue id — the terminal node auto-ends the dialogue, D21),
# pays an egg + a +100 gold grant on completion. The gold reward uses the
# `add` incremental action (D33) — the D29 language gap (set-state is absolute,
# D20) is closed; questProgress stays an absolute set-state.
