Workout TrackerWorkout Tracker

The session this tracker is for, as a plan document (planVersion 1): the day, a title, optional session type, phase and target duration, up to eight briefing lines, and up to sixteen blocks run in `order`. A block holds items and may be a superset or circuit with rounds. An item names a movement with a stable kebab-case canonicalId (the key that joins weeks, never the display name) and one component: sets, pyramid (ramping steps), sided (left and right rows), countdown, stopwatch or interval. Loads and reps are the pre-filled values, in the item's loadUnit or else the unit slot. Every new tracker fills this slot.

The unit loads are entered in unless an item names its own loadUnit: kg or lb. Declared, never converted on the page beyond the one pounds column the record keeps for queries.

The session title. Only read when there is no plan (a plan carries its own title); kept so trackers built before the plan document still render.

The older, simpler shape: exercises in order, each with a name, target sets and a note. Only read when there is no plan, and drawn as straight sets. New trackers use plan instead.
