What it is
Trial-countdown rebalancing. TrialCountdownHero was anchored to a 7-day trial mental model with hardcoded TRIAL_DAYS=7 + tier thresholds tuned to 7 days, but Mark LXXV had bumped TRIAL_DAYS to 14. Rebalanced thresholds (last_call ≤1, urgent ≤4, focus ≤9, encouraging ≥10) + updated 'Seven days' copy to 'Two weeks'. Real bug caught while auditing dashboard surfaces.
