/* Shares the accent color generated reports already use (research_workflows.
   _CORE_REPORT_CSS's own #44c8ff) so the app shell and the report iframes it
   embeds still read as one product - kept deliberately unchanged by the
   ui-ux-pro-max redesign below even though its own generated palette suggested
   a green accent, since switching just this file would have visually split the
   shell from every report page's own extensively-tuned dark theme. Everything
   ELSE (background layering, borders, muted text, typography) follows the
   generated "equity research / financial terminal" design system: a proper
   navy/slate depth scale (was flat near-identical grays before) and the
   Exo/Roboto Mono heading+body pairing. Motion in this file follows one rule
   throughout: eased, not linear (cubic-bezier(0.16,1,0.3,1) - fast start, soft
   landing) - and every animation/transition is neutralized under
   prefers-reduced-motion at the bottom of this file. */
