/* ==========================================================================
   THE REGISTER — design system for the WhatsApp Cloud API control panel
   ==========================================================================
   Direction: a back-office ledger register, not a consumer chat skin.
   Conversations are entries to reconcile; broadcasts are batches; template
   and flow states are ink stamps. Light mode is daytime ledger paper.
   Dark mode is the same room at night under a single banker's-lamp glow.
   Color is quarantined to stamps and the one urgency accent; everything
   else is ink, rule lines, and tabular numerals.
