/* ─── Work Center (work-items U6) — page styles ──────────────────────
 *
 * The global Work Center + agent Work surface over the Work Item Ledger.
 * Naming discipline: this is "Work Center" everywhere — never "work
 * ledger" (the Finney-loop Completed-lane ledger is an unrelated concept
 * that keeps its name).
 *
 * Accessibility invariants carried by THIS stylesheet (pinned by
 * Comprehensive Test Suite/work-items/work-center.test.ts):
 *   • visible focus — a real :focus-visible ring on every interactive
 *     element (outlines are never suppressed without a replacement);
 *   • non-color state cues — every state chip/indicator carries TEXT
 *     (the chips render words; color is reinforcement only);
 *   • reduced motion — @media (prefers-reduced-motion: reduce) turns
 *     off the page's transitions/animations.
