   作曲的逻辑 / music track
   Reuses the cosmos component sheet verbatim (which itself @imports
   the shared RL base sheet and defines kicker / source-note /
   takeaway / position-grid / lesson-flow / mini-flow / trade-table /
   lesson-grid / toc-grid / widget / kpi-grid). No music-specific
   classes needed — Web Audio widgets use the standard .widget shell,
   .primary buttons, range inputs, and .dist-canvas.
