Apply wabi-sabi restraint — the discipline of leaving things out, of resisting decoration, of letting empty space and silence do design work. Use when designing reading-focused interfaces, paring back accumulated clutter, choosing between decoration and absence, or evaluating whether each element earns its place. Restraint is the often-overlooked half of wabi-sabi: the imperfection side gets attention, but the principle is equally about modesty and the elegance of what's not there.
