/* =============================================================================
   UPBI Hub Tracker — foundation: design tokens, app shell, primitives

   VISUAL SYSTEM
     Ported from the main UPBI dashboard so the Hub reads as the same product.
     See UPBI-VISUAL-PARITY-AUDIT.md §3 (tokens), §4 (components), §9 (the 38-row
     differences table this file implements).

     The identity is UPBI navy #071d33/#0b2b4a with a TEAL accent #0d9488 — NOT
     Notre Dame navy + gold, which is a different institution's palette and appears
     nowhere in the dashboard. Every --nd-* token and every gold rule was retired.

   CSP
     No style="" attribute, no element.style.*: the Content-Security-Policy carries
     no 'unsafe-inline'. Computed widths use the .hub-w-* utilities at the end.

  /* ---- COMPATIBILITY LAYER ----------------------------------------------
     hub-operations.css still consumes an older token vocabulary across ~180
     screen-component rules. Rather than touch every one of them (and risk
     silently changing a screen nobody re-reviewed), the old names are mapped
     onto the new palette here, in one place. Anything named --nd-* is a Notre
     Dame token that no longer exists on its own terms — it now resolves to the
     UPBI equivalent, so no rule renders unstyled and no gold survives.
     New CSS should use the tokens above; these exist to be deleted later. */
