/* ── KPI STRIP ────────────────────────────────────────────
   Compact horizontal row of metric cards — small uppercase label
   + large mono number. Used on Flight Management (above the
   table), Resource Allocation (above the Gantt), and any other
   module that needs a quick situational summary at the top of a
   data view. Distinct from .stat-strip, which is a heavier
   dashboard-tile pattern.

   - Each metric is one .kpi-card; cards are click-targets by
     default (cursor: pointer + hover wash). Add .is-static for
     a non-interactive card.
   - Add .is-clickable + an onclick handler for click-to-filter
     or click-to-jump behavior; the same .is-active state shows
     when a card is acting as the current filter.
   - Value colour modifiers: kv-good (green), kv-warn (amber),
     kv-bad (red), kv-blue (accent), kv-muted (faded). The 'muted'
     variant also drops one type step so 0/— don't dominate.
   - .kpi-sep inserts a vertical hairline between logical groups.
   - Dark-themed pages (Resource Allocation, the operations
     dashboard) opt into the dark palette by adding .is-dark on
     the strip; works without changing the page-global theme.
