1Persistent top nav — logo, primary nav, search, auth. Same across every screen so the IA stays predictable.
2Browse sidebar — quick-jump categories (Trending, Newcomers, Top 10, Festivals, Following). Replaces the old "Advanced search" link nobody clicked.
3Sort tabs — fans default to "Soonest" but can switch to Trending / Newcomers / Top picks without leaving the page.
4Show card — image · date · band · supporting acts · venue · genre tag · price · CTA. Designed so every show is decidable in 3 seconds.
5Right-rail filters — chips for Genre, Location, When, Price. Always visible, no modal needed for the common case.
