   "Still": the Back to Even design language, web edition.
   Tokens mirror app/BackToEven/AppConfig/Theme.swift: a misty Day palette
   (and Dusk for dark mode), one sky-blue accent, coral only for help.
   Type: SF Pro Rounded where the system has it (Nunito elsewhere) for
   headings, the system face for reading. No all-caps, no tight tracking.
   Mascot: Pip, the black cat, drawn from the app's own renderer.
