/* ═══════════════════════════════════════════════════════════════════════
   EXALYTICS — theme "Ledger Pro"

   Design principles, so future edits stay coherent:
     · Chrome is neutral. Colour is reserved for data and for direction.
       Buttons are ink, never brand — a CTA must not out-shout a chart.
     · Two-tier accent: --accent passes AA for text (5.3:1); --accent-bright
       carries graphics (3.8:1). Using one mid-teal for both is what pushes
       most products into failing link contrast.
     · Every figure is tabular. Columns that don't align read as amateur.
     · Sans for interface, serif only where the content is written prose.
