/*
 * AI Lab design tokens (SK-T). One file, shared byte-for-byte by Fleet
 * (fleet/portal/static/) and www.ai-lab.com (sites/www-ai-lab/app/).
 * Spec: PLAN-fleet-skin-and-site.md §1. Ratios: README.md. Frozen; a change needs a new order.
 *
 * :root is light. Dark applies when the system asks for it and the page is not
 * forced light, or when theme-toggle.js forces it. The two dark blocks below must
 * stay byte-identical (tests/test_ai_lab_tokens.py), so the media one is not indented.
