/* ==========================================================
   PHASE 5 — Website Analytics
   Builds on global.css and admin.css (shell, dashboard-topline,
   stat cards, skeletons, panels, dashboard-error). Only
   analytics-specific pieces live here: the range tabs, live-now
   panel, hand-rolled SVG trend charts, and the bar-list rows used
   for top pages / sources / devices / browsers / landing pages.

   No charting library is used — charts are small inline SVGs built
   from real aggregated data, matching "no giant charts, no clutter,
   premium agency analytics dashboard" from the design brief.
