/*
 * Spark application shell — sidebar, drawer, topbar, account menu, theme toggle,
 * navigation, skip link and focus ring. Shared by the portal and the platform admin.
 *
 * Rules: class-scoped selectors only (no element resets), tokens from tokens.css,
 * rule order preserved from the original spark.css so the portal cascade is unchanged.
 * Breakpoints: >= 1300px wide, <= 1100px compact, <= 900px drawer, <= 560px phone.
 * The drawer breakpoint (900px) must match the media query in spark.js.
