/*
 * Facilis UI — shared design system for customer demos.
 * Cribbed from facilisplatform's index.css :root tokens.
 * Vanilla CSS only — no Tailwind, no build step.
 *
 * Anti-slop rules:
 *   - No gradients on chrome (only on functional things like progress bars).
 *   - No shadows on cards except the glass shadow.
 *   - Single accent color (#6E8BFF). Data colors signal value, not decoration.
 *   - All radii from the scale below. No ad-hoc 4px or 6px junk.
 *   - Borders are 1px, semi-transparent white. Never solid grey.
