/*
 * HAi1Y Design System for the web: the same components as hai1y-design-android. The whole palette is HAi1Y; each app
 * adds one brand through the --h-brand-* tokens (Gringotts: gold and vault navy, in gringotts-web's brand/gringotts.css).
 * Color carries meaning (Chris, 2026-10-23): blue (--h-primary) is only what can be tapped; purple (--h-hai1y) is HAi1Y
 * itself, never an action; values are text, bold with fixed-width digits; teal is calm information.
 * Put class "h-theme" on <html> (or any container). Light by default; dark with the viewer's system setting,
 * data-theme="dark" on the root, or the h-dark class.
