/* =========================================================
   ANALYTICS PAGE
   Page-specific layout for the Analytics dashboard: hero band,
   split FB/IG KPI grids, trend/donut charts, top-posts spotlight.
   Shared card/list chrome (.kpi, .panel, .inbox-list) stays in
   their own component files — this file only holds what's unique
   to this page.
========================================================= */

/* One vertical rhythm for every top-level block on the page — gap does the
   spacing, so no block needs its own margin, and stacking two .panel
   siblings here never double-spaces against panels.css's own `.panel +
   .panel` rule. */

   the panel doesn't carry a band of dead space under a short chart. A
   floor, not a fixed height: chartFbPosts/chartIgPosts also carry a
   legend appended below the chart (see renderPostEngagementChart), which
   a fixed height would clip — min-height lets the box grow for that
   while still giving chartCompare's bare, legend-less chart a tidy size. */

   Same flat, divided-cell language for both: one panel, cells separated

   card — keeps a labelled number reading as one thing everywhere it
