   Fleet Ops — enterprise-grade trends/health dashboard at /ops.

   NOTE: global stylesheet (linked from _Host.cshtml). The scoped-CSS
   bundle (.razor.css) was failing to apply for this page in dev runs —
   the bundle compiled and was served, but the scope attribute wasn't
   reaching the rendered elements. Rather than keep chasing that, ship
   globally. Class names here are page-specific (.ops-*, .hero-*, .kpi-*,
   .lb-*, .spend-*) so cross-page bleed is minimal.

   Visual targets (think Stripe / Linear / Datadog, not generic Bootstrap).
