Side B adds a substantial new end-to-end capability: a CopyGardenRank UI action, server handler, markdown formatter, clipboard JavaScript response, UI buttons across garden views, and integration/browser tests covering the feature. Side A improves row coloring by switching from list-position gradients to per-group score normalization with good helper extraction and tests, but it is a focused presentation enhancement rather than a broad new user-facing capability.
