/* ═══════════ v3.6.0 · PROGRESS — the Explorer and the Dock (Arrick, 2026-08-25) ═══════════
   Desktop = the Planner's shell (a full-height rail, the Explorer above the Dock at one
   width; the Explorer takes every pixel the Dock doesn't). Phone = the page layer. The
   chart is an SVG stretched to its box with non-scaling strokes; every label is HTML
   placed by percentage, so it resizes without distorting. All new classes wear px-. */
