Describe your cover frame candidates and get them judged at the size people actually see them: a self-contained HTML contact sheet at real grid and shelf dimensions, a legibility score for every text element, a ranked pick with the deciding reason, and redraw instructions for the runner-up.

Most players lose games on the clock and blame the wrong phase. Clock Leak reads your Lichess games and measures exactly where your time goes - opening, middlegame, late game - against 93 real peers and a 27-player 2300+ panel. The popular advice "play faster in the opening" has zero measured effect (r=0.11). Middlegame overspend does (r=0.41). One numeric action per report, traced to your own data. No engine coaching, no rating promises.
