/* =============================================================================
   Calculation Hub Platform Visualization System
   -----------------------------------------------------------------------------
   PURPOSE
   - Shared deterministic chart presentation for case studies, custom reports,
     presentations, scenario comparisons, and future tool adapters.
   - Owns semantic series colors, chart frames, axes, plot geometry, legends,
     summaries, mobile density, and accessible data-table hiding.

   GOVERNANCE
   - Records/models choose semantic roles, never raw colors.
   - Surface adapters choose display profile, never chart geometry.
   - No mortgage formulas, benchmark thresholds, or scenario ranking live here.
