/* ============================================================================
   Fidelity ETRM — "Ledger" design language
   ----------------------------------------------------------------------------
   The app shares its identity with the client-facing position report
   (Application/Services/PositionReportHtml.cs): ink and paper surfaces, the
   Fidelity navy, a serif reserved for titles, tracked uppercase eyebrows and
   hairline rules. Colour is spent on meaning only — commodity, status and
   direction — and the accent is spent on interaction only.

   Every component is in-house (Components/Ui): this file is the whole of the
   visual layer, there is no third-party component CSS beneath it.

   Structure
     1. Tokens (dark = default, light = [data-theme="light"])
     2. Base + typography
     3. Shell (sidebar, top bar, content)
     4. Page scaffolding (header, panel, stat, filters, toolbar)
     5. Data (tables, badges, status, figures)
     6. Controls (buttons, fields, pickers, segmented, switch, check, range)
     7. Overlays (popovers, menus, dialogs, toasts, tooltips)
     8. Composites (tabs, disclosure, alerts, chips, progress, avatar)
     9. Auth pages
    10. Prose, empty states, skeletons
    11. Layout grid + utilities
    12. Motion, focus, print

   Rules below the token blocks use var(--*) only — never raw colour — so the
   two themes stay in lock-step. ChartTheme.cs mirrors the chart tokens.
