/*
 * Sakura Theme  --  Claude's Choice
 * Named for the app: neko is Japanese for cat.
 * A theme inspired by the quiet beauty of Japanese graphic design.
 * Ma (negative space), wabi-sabi (beauty in imperfection),
 * and the restrained palette of ukiyo-e woodblock prints.
 * Warm grays, muted pinks, deliberate whitespace, and a sense of calm.
