Interval Today
A training home screen where the readiness figure is derived from resting heart rate, heart rate variability and sleep, with all three inputs and their weights shown under it rather than a score arriving with no working. Today's session carries a duration reduced from its blocks and its planned time in zone as a stack in the five zone colours, and the week strip colours each day by the highest zone holding a tenth of that session.

The rule this design follows
It ships exactly as previewed: same colors, same type, same copy, same motion. The prompt tells your agent to build that, and not to adapt it to your existing theme.
