/* FirePay approvals: Code 3 house style (Slab) for product UI, dark-first.

   Tokens: the Slab values the marketing site ships at code3-website d788f45 (src/styles/global.css),
   which hand-maintains them (it does not import code3-design-system), copied here by value. The
   dashboard differs in three deliberate ways, each from the product-UI canon:
     1. Dark is the default theme; light follows prefers-color-scheme or the in-page switch.
     2. It has adopted the green/red split (Design-Guardrails): green #009B52 is the action (navy
        label), amber #FFB000 is outstanding (navy label, fill only), red #FF4122 means something is
        wrong, and Stop all sending is the alarm control. The focus ring is neutral, never red.
     3. The type scale is the product scale of ui-polish (32/24/18/16/14/13/12), not the site's.
   Every text pair is measured in test/dashboard/contrast.test.ts against every surface it can land
   on, in both themes (WCAG 2.2 AA: 4.5:1 text, 3:1 control boundaries and the focus ring).
   No storage: the theme switch lives in memory only, like the site's. */
