/* ==========================================================================
   SOS ISP Manager — Global Theme Skin (Iteration 1)
   ------------------------------------------------------------------------
   Loaded LAST in layout.php so it wins specificity battles against legacy
   per-module stylesheets. This file establishes the unified visual system:
   deep indigo/violet gradient sidebar, soft frosted topbar, light blue-grey
   canvas, white rounded cards with soft shadow, gold accent, rounded pill
   buttons, modern tabs with active underline, compact tables, badges, and
   responsive behavior. No markup changes required — every page that goes
   through src/Views/layout.php inherits the look automatically.
