/* Leadynox Media Platform — Admin Dashboard (Phase F1: Enterprise Design System)
   Self-contained, no external fonts/CDNs/UI libraries — consistent with
   this codebase's no-Composer/hand-rolled convention. Every selector
   already used across every existing admin view is preserved below
   (buyers/campaigns/publishers/analytics/dashboard/auth) so every page
   continues working unchanged — only the values behind those selectors
   changed. New component sections (dropdown menu, notification panel,
   modal, progress) are appended at the end, actively used by later
   phases (Phase F2's modal-driven dialogs, Phase H's cap-usage progress
   bars). Dark theme is the default; a light theme (the platform's
   original palette) is available via [data-theme="light"] for the
   Phase F1 theme toggle. Phase I production hardening removed the
   Drawer and Loading Skeleton component CSS (built "for future use" in
   Phase F1 but never wired to any view) and a few unused single-purpose
   variants (.trend-down/.trend-flat, .progress-bar-success,
   .form-feedback-invalid/valid, .form-control.is-invalid/valid,
   .loading-placeholder) after confirming zero references anywhere in
   this codebase — re-add only alongside the view that will actually use
   them. */

:root {
    /* Tells the browser to render native, OS-drawn controls (a <select>'s
       own dropdown popup, date/time pickers, scrollbars) in dark mode —
       without this, every <select> on this dark-themed page opened a
       plain white dropdown list (owner-reported, 2026-08-19), since
       those popups are drawn by the OS/browser itself and never inherit
       page CSS colors on their own. The authenticated app layout
       (admin/views/layout/app.php) has no light-theme toggle wired up
       (only the guest/login layout does, unused here), so this is safe
       to set unconditionally rather than needing a [data-theme] guard. */

   already inside .table-responsive is unaffected (that wrapper already
