   RosterWarden — mobile-first stylesheet.

   The Sixth Day Studios dark palette shared with InvoiceWarden and RamWarden
   (near-black surfaces, teal accent). Dark-only: contrast is kept high so it
   stays readable on a phone outdoors. Everything is token-driven.

   System fonts throughout, deliberately: this is an offline-first installed app
   and a webfont request would block first paint on a bad connection.
