 * The Slate relay status page (ADR-91). Styled as a natural extension of the
 * desktop app's design system (ADR-46/47): the catppuccin-frappe palette in
 * dark, latte in light, Slate's Inter + JetBrains Mono stacks (via the same
 * system fallback the Mantine theme uses — the strict CSP forbids CDN fonts),
 * cool near-monochrome with a single slate-blue accent. Restraint is the point:
 * a zero-knowledge relay's front door should feel quiet and honest.
