The FN-4286 dashboard text-token guard requires command-center secondary copy to use --text-muted, not the deprecated secondary text token or raw color fallbacks.

FNXC:CommandCenterStyling 2026-06-19-18:30:
FN-6690 fix: Command Center CSS was authored against a numeric token scale (--space-1..--space-36, --font-size-*, --border-width*) that this design system never defines, so ~186 var() refs resolved to nothing and the whole view rendered collapsed/unstyled on desktop and mobile (raw run-together tabs, no padding). The dashboard uses the NAMED 4px spacing scale only: --space-xs(4) sm(8) md(12) lg(16) xl(24) 2xl(32), with calc() of named tokens for larger values (house style, e.g. calc(var(--space-2xl) * 7 + var(--space-lg))). Font sizes are raw rem (no --font-size-* tokens exist) and border widths are raw px (--border is a color, not a width). All Command Center CSS is remapped onto these. A token-validity guard test (CommandCenter.token-validity.css.test.ts) now fails if any component CSS references a custom property not defined in styles.css, so this class of bug cannot recur. The bug slipped past the recent FN-66xx work because those tests ran in jsdom, which does not resolve CSS custom properties or compute layout.
