/* VibeStack Account - the whole stylesheet.
 *
 * The shared VibeStack look (the same tokens as VibeStack Dev and VibeStack Host): Inter served from
 * /assets/fonts (nothing is loaded from elsewhere), a top bar, rounded cards with a soft shadow,
 * pills, buttons, forms with a focus ring and coloured messages. Light mode is Catppuccin Latte, dark
 * mode is Tokyo Night; the page follows the computer's own setting (prefers-color-scheme), so there
 * is no theme switch. Tables turn into stacked cards on a narrow screen. The patterns that later
 * pages must reuse are listed in docs/PRODUCT.md, "Shared UI patterns".
