Analytical day
Calendar charts use your local time. Readings before the boundary stay with the previous physiological day; sleep is assigned by wake time. Absolute source timestamps are never changed.
View
Essentials keeps the navigation to the daily surfaces; Observatory opens every power view. All pages stay reachable by URL in both modes.
Pinned signals
Nothing pinned - the Today grid shows the curated defaults. Star any signal in the Library to build your own grid.
