/*
 * KidSec design system — tokens + base components.
 * Extracted from the hand-made mockups (design review, 2026-09). Two scopes:
 *   .ks-shell            customer-facing (family + institution) — blue/indigo
 *   .ks-shell--platform   Velvio internal ops panel — near-black + violet
 * Screens built in later phases should compose these classes rather than
 * writing one-off styles, so the whole app stays visually consistent.
