/* Best AI Girlfriend App: one stylesheet, no web fonts, no JavaScript.
   Layout: a reference site. On wide screens a quiet left rail lists every entry beside a 46rem
   reading column; on phones the rail folds away and each entry ends in its own reading path.
   Palette borrows heyGF's gold and wine; neutrals lean slightly toward the wine.
   Serif for reading, system sans for everything you scan. */
