/*
 * Chordizone status page - design tokens from docs/07-design-system.md.
 *
 * Values are the real ones from the design system, not eyeballed:
 *   light  background gray-100 #ECECEA, surface white, surface-alt gray-50 #F0F0F0,
 *          border gray-200 #DEDFDD, text gray-900 #1E1E1E, secondary gray-500 #888A8D
 *   dark   background #121212, surface gray-800 #2E2E2E, elevated gray-900 #1E1E1E,
 *          text #FFFFFF, secondary gray-500 #888A8D (single-valued), border #3F3F3F
 *
 * Status colours:
 *   operational  semantic/success #166534 light / #22C55E dark.
 *                CAVEAT: doc 07 marks these PROVISIONAL - they are not in Figma and still need
 *                design sign-off (DEV-255). They are used here rather than invented, and both clear
 *                WCAG AA on their own page background per that doc's contrast note.
 *   degraded     tuner/near #D78324 (single-valued, real token)
 *   outage       Accent/Red #BB3846 (single-valued, real token - the retired brand red #CD4F5C is
 *                NOT used anywhere)
 *   no data      the secondary text grey, deliberately low-contrast so it reads as absence
 *
 * Type: Suisse Int'l and Geist are the design's Latin families but are not licensed for the web here,
 * so this uses the same system stack as the served legal pages (server/presentation/resources/legal).
