/*
 * Kebrio UI — shared look for KebStud, KebFin, KebVest and KebWork (KR-PRD-001).
 * Plain CSS on purpose: KebFin is a static site with no build step, so it can
 * link this file directly. The Vite apps import it from their entry file.
 *
 * v2 (2026-11-07, Iris after KB's reference dashboards): soft white cards on a
 * tinted canvas, big thin titles and numbers, light sidebar with a dark pill,
 * pill buttons, soft-tint status tags, one data accent per app.
 *
 * Rules this file encodes (G1–G9, as amended by v2):
 *   G1 at most 6 cards per screen: white, borderless, 20px radius, soft shadow,
 *      on the app's tinted canvas; hairlines group content inside a card; never nested
 *   G2 one number strip per page (.k-strip), 36px light numbers, small grey units
 *   G3 status = dot + text (.k-status) or one soft-tint tag per row (.k-tag), text >= 4.5:1
 *   G4 at most one notice bar at the top (.k-notice)
 *   G5 one dark pill primary button per page (.k-btn.is-primary), round icon buttons
 *   G6 no greeting: date + 40px light title + one useful summary line (.k-head)
 *   G7 Geist + Geist Mono, 1.5px line icons
 *   G8 buttons 40px (44px on phones), shadows only on cards and overlays
 *   G9 apps keep their brand: set --k-canvas, --k-accent (data only), --k-brand
 *
 * Every app-specific value is a variable; apps set them on :root after
 * importing this file. Fonts are served from this package (no font CDN).
