/* ==========================================================================
   Navigator console — common shell (UX overhaul Phase U1)
   --------------------------------------------------------------------------
   Loaded AFTER styles.css on index.html (/ and /hanul). Spec: docs/UX_U1_SHELL.md

   Rules
   - CSS Grid with fixed regions: top bar 48px · left tool panel (collapsible) ·
     centre workspace · right commander (360–560px, resizable, collapsible) ·
     bottom mission timeline. Opening/closing a panel shrinks the workspace;
     regions never overlap.
   - Floating things live ONLY in workspace slots (#nv-slot-*), >= 16px inside
     the workspace edge; items in one slot stack (flex), slots are separate grid
     cells, so nothing overlaps.
   - z-index ONLY via the 6 --nv-z-* tokens. Colours ONLY via var(--nv-*)
     (tests/test_layout_tokens.py forbids literals in shell/*.css).
   - Fixed sizes: long text ellipsis / wrap / internal scroll; long URLs wrap
     (overflow-wrap:anywhere).
   - Moved legacy panels keep their ids; the overrides below are id-scoped
     (#nv-shell #x) so they beat styles.css without editing it.
