estimateRunDuration() computes a per-run ETA from a target count, a fire time, and an assumed per-account send rate (40/min, mirroring the bot env). Adds a 15% buffer with a 1-minute floor. Pure helper, covered by 6 round-trip tests including the rate-defaults path. Header CTA buttons on /accounts and /reminders are now size="lg" rounded-full pills with a shadow that lifts on hover. Mobile shows just the plus icon (label collapses) so the button doesn't dominate narrow screens. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
