/* Nexus Admin (SCR-002..017), redesign: IBM Plex Sans for the UI, IBM Plex Mono for figures,
   warm neutrals, one blue accent. Every colour is a custom property on :root; the dark palette
   applies under prefers-color-scheme unless data-theme="light" pins light, and under
   data-theme="dark" whatever the OS says (src/ui/theme.ts). Loaded from a file only: the CSP has
   style-src 'self', so there is no inline style anywhere, and SVG charts size themselves with
   attributes. */
