USR369 direction 09/01/26, mid-workout: cardio has three sections he can go into (Cardio 1, 2, 3). Within each section there's Warmup and Main. He wants Warmup and Main to 'roll up' -- exact meaning not yet confirmed (could mean: combined/summed total duration displayed, or merged into a single entry). Ties directly to item #24 (Cardio Session restructure, already open) -- may be the same underlying ask with more detail, or a genuinely separate structural point (3 distinct cardio slots vs. 1 session with 3 sub-entries) -- needs reconciling with #24 before either gets built, not treated as a third competing spec.
