Side A fixes a concrete usability gap by making the pinned icon in ranked child groups perform the existing unpin flow (`set_garden_pin`), wiring the required redirect path through rendering, updating styles for the new button, and adding an end-to-end browser test covering both ranked-list and HUD unpin behavior. Side B adds a useful markdown copy feature with new UI actions, rendering, and tests, but it is primarily an additive convenience feature rather than resolving an inconsistency in core interaction.
