/*
 * KuuniFinance — theme.css
 *
 * Design tokens, reset, and the components shared by both pages. Page-specific
 * rules live in dashboard.css and tools.css.
 *
 * Palette, type and button shapes match the Kuuni Partners site (theme.css at
 * the site root) so the two read as one brand. Fraunces/Inter load from Google
 * Fonts with full system fallbacks, so the app still works offline.
 *
 * Money figures are always monospace with tabular numerals so columns of
 * dollars line up like a ledger.
