- Better timing of audio cues - Audio ducking instead of pausing - Bug fixes for handling empty sessions

Supersets: exercises can be grouped into back-to-back chains with a short configurable rest between them, color-coded in both the workout editor and session player. The whole block moves together when reordering. Audio beeps & background timer: a 3-count beep plays before each rest ends, works with the screen off. The timer now runs on wall-clock time so it no longer drifts when the screen locks or you switch apps. Rest overtime: instead of auto-advancing when rest ends, the timer ticks upward so you decide when to go. Triggerable manually (long-press pause) or automatically in the background. Logged session details: tap any entry in the history list to see a full breakdown of every workout and exercise logged in that session. Unified edit model & propagation: editing default items no longer creates a silent fork; nested edits (exercise → workout → session) are held locally and committed in one shot. The propagation prompt now shows a checkbox per consumer instead of all-or-nothing. 90-day trash: deletes are now reversible for 90 days, sync across devices, and show which sessions use the item before you confirm.
