   Distribution Gaps™ — Global Music Footprint™ Workspace
   Board Directive 2026-07-17 — Responsive-First Implementation
   ═══════════════════════════════════════════════════════════════════════
   Loaded only by /workspaces/global-music-footprint.html. Reuses design
   tokens from royalte-workspace.css (--mc-*, --rds-*); does not redefine
   them. Accent: --mc-blue (GMF workspace accent, ws-dept--global).

   Canonical viewport tiers (matches royalte-rds.css):
     Executive Desktop™    > 1024px
     Executive Tablet™    641–1024px
     Executive Mobile™     ≤ 640px

   Structure:
     § 1  Summary section (beneath the map)
     § 2  Full-list drawer / bottom sheet
     § 3  Search + filter chips
     § 4  Territory list rows
     § 5  Territory detail sub-panel
     § 6  Responsive overrides (tablet, mobile)
