/* brand.css — A!thera Partners design system.
 *
 * The single source of truth for the brand: web fonts, colour tokens, type
 * scale, and the primitive components (buttons, cards, tables, container).
 * Nothing downstream may hardcode a colour or a font — everything references
 * the variables and utility classes defined here.
 *
 * Voice reminder for copy (enforced in markup, not CSS): senior strategist
 * briefing a COO — clear, structured, understated. No emojis. Forbidden words:
 * disruptive, revolutionary, game-changing, synergy, leverage (verb), unlock,
 * harness the power of, next-generation, cutting-edge, seamless, robust.
