   训练的逻辑 / training track  (The Logic of Training — how the body adapts)
   A SCIENCE track (not a competition) in 通识·科学与人文 (grp-tongshi),
   sibling to cooking / chemistry / psychology; the "how athletes are built"
   prequel to the 运动·竞技的逻辑 sports group. Reuses the cosmos component
   sheet verbatim (kicker / source-note / takeaway / position-grid /
   lesson-flow / mini-flow / trade-table / toc-grid / widget / kpi-grid /
   dist-canvas). Widgets draw the stimulus-recovery-adaptation curve,
   dose-response, rep continuum, energy systems, etc. procedurally on a
   .train-canvas — no images.
