/*
 * Version 3 -- Home landing page.
 *
 * Uses the shell's existing tokens throughout and reuses the Force Measurement
 * metric-card anatomy for the KPI strip rather than declaring a second one;
 * only the Home-specific layout lives here.
 *
 * Status is never communicated by colour alone: every system card states its
 * condition in words, and the tone modifier only tints a border beside that
 * sentence.
