/*
 * PushPel Internal Console — shared design system.
 *
 * One source of truth for design tokens, typography, layout, the shared header/nav, buttons,
 * forms, tables, cards, and status pills. This replaces the three drifting per-page stylesheets.
 *
 * Aesthetic: a considered, trustworthy accounting-firm look — deep ink navy on warm paper, a
 * single restrained sage accent reserved for verified/positive signals, a real type scale pairing
 * a quiet serif for display headings with a precise sans for the working UI. No gradients, no
 * decoration for its own sake. Accessible: visible focus rings, sufficient contrast, semantic
 * landmarks, and a respect for reduced-motion.
 *
 * Self-contained: system font stacks only (no external CDNs / web fonts), so the asset-presence and
 * no-external-CDN tests stay green and the console works on a private network with no egress.
