/*
 * CallOS Design System — global visual upgrade.
 * Loaded on every page via _Layout.cshtml, right after brand.css. Purely additive/refining CSS —
 * targets existing Bootstrap/app classes already used everywhere (.card, .btn, .table, badges,
 * .dashboard__table, sidebar/header) so every page gets the same premium treatment without any
 * page's HTML or JS being touched. Page-specific <style> blocks still load after this and win on
 * anything they explicitly override.
