/* Grain — the native app's look (Design/GrainTheme.swift). The iPhone app is dark everywhere: grainBg #0D0C0A,
   grainCard #1F1C17, grainAccent #C99339 (the AccentColor), grainText #F0EAE0, grainMuted #6E6558, a warm centre
   bloom, a top vignette and animated film grain; light serif for writing (New York), monospaced caps for labels,
   ultra-light serif for big numbers. Dark is the default here too; html.paper is the web-only Light appearance (warm
   paper, the same amber). Alerts, dialogs and the NavigationStack sheets follow whichever Grain is showing. */
