/*
 * Design system.
 *
 * Direction: modern developer infrastructure / diagnostic tool. Calm, dense, legible.
 * Explicitly NOT: hacker dashboard, antivirus scareware, generic AI startup, enterprise
 * security suite. Information hierarchy over decoration.
 *
 * Rules held to throughout:
 *   - No gradients, no glow, no shield iconography, no giant hero.
 *   - Severity colour is an accent on a neutral surface, never a filled alarm-red panel.
 *   - Colour never carries meaning alone: every status has a text label.
