/* ============================================================
   Brand & Store — Traffic Overview  (bs-tro-*)   · route #traffic-overview
   OV-18 (PLAN-new-pages.md WU-1). Page-scoped under
   body[data-portal="brand-store"]. DESIGN TOKENS ONLY — the spec's
   hardcoded #2563EB/#16A34A/etc. map to --color-action / --color-success
   / --color-danger / --text-* / --bg-* so both themes resolve correctly.

   The KPI grid, trend wrap, details table, delta pills, empty-state and
   .bs-tr-section chrome are REUSED from bs-store-traffic.css (loaded
   alongside) via the shared .bs-tr-* classes. Only the net-new
   Conversion Funnel viz gets its own .bs-tro-* classes here, plus a few
   page-local control helpers (compare-custom row, CR chip, P2 picker).
   The spec's literal Shopee #EE4D2D / TikTok dark badge colors are kept
   for the brand chips only (platform brand identity), as the live
   bs-store-traffic page does for its platform pills.
