Timers and time zones that respect the clock

The countdown and pomodoro timers do deadline math against the real clock instead of counting ticks, so the face is right even after the tab sleeps. A gentle chime marks zero. Pomodoro keeps today's focus count in your browser and suggests the next phase; every fourth break is the long one.

The time-zone planner lines up cities against your local hour using the browser's own IANA zone database, so daylight saving stays correct on its own, with the polite 08:00–18:00 window marked. Week numbers shows today's ISO week and the whole year's map — the answer to the only question anyone asks in January.
