/* ============================================================
   SIDE-NAV RAIL (v2) - canonical source for per-app replication
   ------------------------------------------------------------
   Activated by html[data-skv-nav-mode="side"]. The rail DOM lives inside
   #skv-header and is display:none by default, so TOP MODE is byte-identical
   to today (no rule below touches a non-side-scoped selector). Desktop rail
   is gated >=961px; mobile drawer <=960px (matches the existing top-mode
   hamburger breakpoint). Width collapse is driven by .skv-nav-collapsed on
   <html>. Active link = filled glass pill (NO left-edge bar / ::before).
   Slate (#5C88B0 / --skv-accent) is the only accent; gold stays a micro-accent.
   v2 additions (all still side-scoped / net-new .skv-rail* elements): rail-owned
   market-status popup (#skv-rail-ms-popup, a clone of the top widget), rail-owned account menu
   (.skv-rail-menu in .skv-rail-chip-wrap), Theme row aux (.skv-rail-link-aux),
   carets, and a side-scoped re-anchor of the shared #skv-notif-panel as a
   left fly-out near the foot bell.
