When term_cols >= 80, right side shows jj show --summary of the currently highlighted revision (header stripped — just description and the M/A/D file list, with description capped at 3 lines). Per-row preview is cached, so navigating back to previously-viewed revs is instant. Bumps the viewport floor to 15 rows (max = full terminal) so the preview has room to be useful.
