/* TradeLytics design system.
   Direction: a clean, confident market-data reader -- legible at a glance
   on a phone (this is the whole point: SEO visitors land on a phone,
   check one number, leave or bookmark). Deep teal-navy base (distinct
   from any other product's palette), single amber accent for the brand
   mark and CTAs, up/down colors doing real work (green/red on signal,
   never decorative). Mobile-first: base styles target narrow screens,
   wider layouts added via min-width media queries, not the reverse. */
