/* AI Trading Lab - component library, built on tokens.css.
   Every visual element the app uses lives here as a reusable class, not
   duplicated per page - a rebrand or a redesign changes this file, not
   eleven templates. Organised: base -> layout shell -> nav -> primitives
   (buttons, badges, inputs) -> data display (cards, tables, metrics) ->
   AI-specific (status, activity feed, decision cards) -> overlays
   (command palette, notifications, modals) -> auth page -> responsive. */
