/* ══════════════════════════════════════════════════════════════
   GIMS App Shell — Watery v2 (deep water · tan sun-shaft frames · blue actions)
   The reusable chrome every UI page renders inside: section rail (workspace nav),
   header (title + profile chip), first-class login card, content slot, toasts.
   Injected server-side by core/orchestration/page_node.py (shell=True).
   Colours/components come from watery.css; this file is layout + shell structure.
   The launcher keeps its own launcher.css (it predates this and adds sections).
